Abstract: Full-duplex wireless communication is described. In an embodiment, a transceiver device having a transmitter circuit and a receiver circuit receives a data packet sent over a shared communication medium. In the embodiment, the transceiver reads the header of the data packet and starts transmitting an output signal on the same shared communication medium. Embodiments are described in which, whilst the transmission of the output signal is ongoing, the transceiver receives an impaired data signal which is made up of the payload of the data packet and interference from the output signal. In the embodiment, a cancellation signal is derived from the output signal, and this is combined with the impaired data signal to remove the interference and recover the payload of the data packet.

Abstract: A method and an apparatus for uplink transmission using multiple uplink carriers are disclosed. A wireless transmit/receive unit (WTRU) selects a dedicated channel medium access control (MAC-d) flow with highest priority data to be transmitted and performs uplink carrier selection and enhanced dedicated channel (E-DCH) transport format combination (E-TFC) restriction and selection to select a carrier among a plurality of carriers and select an E-TFC based on a maximum supported payload, a remaining scheduled grant payload of the selected carrier and a remaining non-scheduled grant payload. The WTRU then generates a medium access control (MAC) protocol data unit (PDU) for E-DCH transmission via the selected carrier based on the selected E-TFC.

Abstract: A lossless audio codec encodes/decodes a lossless variable bit rate (VBR) bitstream with random access point (RAP) capability to initiate loss less decoding at a specified segment within a frame and/or multiple prediction parameter set (MPPS) capability partitioned to mitigate transient effects. This is accomplished with an adaptive segmentation technique that fixes segment start points based on constraints imposed by the existence of a desired RAP and/or detected transient in the frame and selects a optimum segment duration in each frame to reduce encoded frame payload subject to an encoded segment payload constraint RAP and MPPS are particularly applicable to improve overall performance for longer frame durations.

Abstract: Downlink PDCCH is communicated in a manner that mitigates a UE from decoding the PDCCH on multiple aggregation levels. Ambiguous payload sizes are identified and modified through zero padding with one or more bits based on the payload size. Aggregation level scrambling sequences can be generated such that a receiving UE can accurately identify the aggregation level on which to decode the PDCCH. Indicator bits that signal the aggregation level to a UE can also be included in the PDCCH.

Abstract: Given the ease of alteration of digital data, integrity verification and tamper detection for medical images are becoming ever more important. In this paper, instead of using the conventional irreversible block-based watermarking approach to achieve tamper localization, we propose to incorporate such functionality into the region-based lossless watermarking scheme. This is achieved by partitioning an image into certain non-overlapping regions and appending the associated local authentication information directly into the watermark payload. A region of authentication, which can be flexibly specified by the user, is partitioned into small regions in a multilevel hierarchical manner. Such hierarchical structure allows the user to easily adjust the localization accuracy, and makes the tamper detection efficient. Experimental results demonstrate the effectiveness of tamper localization.

Abstract: Video watermarking is relatively a new technology that has been proposed to solve the problem of illegal manipulation and distribution of digital video It is the process of embedding copyright information in video bit streams In this paper, we propose two effective, robust and imperceptible video watermarking algorithms The two algorithms are based on the algebraic transform of Singular Value Decomposition (SVD) In the first algorithm, watermark bit information are embedded in the SVD-transformed video in a diagonal-wise fashion, and in the second algorithm bits are embedded in a blocks-wise fashion The performance of the two proposed algorithms was evaluated with respect to imperceptibility, robustness and data payload Both algorithms showed similar but high level of imperceptibility, however their performance varied with respect to robustness and payload The diagonal-wise based algorithm achieved better robustness results, while the block-wise algorithm gave higher data payload rate

Abstract: Systems and methods are provided for processing a payload portion of a received signal in a single carrier mode or a multiple carrier mode based on a portion of the received signal. A single carrier signaling portion is received at a first rate, and whether the payload portion of the signal is a single carrier signal or a multiple carrier signal is detected from the received single carrier signaling portion. The payload portion of the received signal is received at the first rate and demodulated in a single carrier mode if the detecting determines that the payload portion of the received signal is a single carrier signal, and the payload portion of the received signal is demodulated in a multiple carrier mode if the detecting determines that the payload portion of the received signal is a multiple carrier signal.

Abstract: The aim of this paper is to determine the optimal trajectory and maximum payload of flexible link manipulators in point-to-point motion. The method starts with deriving the dynamic equations of flexible manipulators using combined Euler–Lagrange formulation and assumed modes method. Then the trajectory planning problem is defined as a general form of optimal control problem. The computational methods to solve this problem are classified as indirect and direct techniques. This work is based on the indirect solution of open-loop optimal control problem. Because of the offline nature of the method, many difficulties like system nonlinearities and all types of constraints can be catered for and implemented easily. By using the Pontryagin's minimum principle, the obtained optimality conditions lead to a standard form of a two-point boundary value problem solved by the available command in MATLAB®. In order to determine the optimal trajectory a computational algorithm is presented for a known payload and the other one is then developed to find the maximum payload trajectory. The optimal trajectory and corresponding input control obtained from this method can be used as a reference signal and feedforward command in control structure of flexible manipulators. In order to clarify the method, derivation of the equations for a planar two-link manipulator is presented in detail. A number of simulation tests are performed and optimal paths with minimum effort, minimum effort-speed, maximum payload, and minimum vibration are obtained. The obtained results illustrate the power and efficiency of the method to solve the different path planning problems and overcome the high nonlinearity nature of the problems.

Abstract: This paper proposes KISS, a new Internet classification method. Motivated by the expected raise of UDP traffic volume, which stems from the momentum of P2P streaming applications, we propose a novel statistical payload-based classification framework, targeted to UDP traffic. Statistical signatures are automatically inferred from training data, by the means of a Chi-Square like test, which extracts the protocol "syntax", but ignores the protocol semantic and synchronization rules. The signatures feed a decision engine based on Support Vector Machines. KISS is tested in different scenarios, considering both data, VoIP, and traditional P2P Internet applications. Results are astonishing. The average True Positive percentage is 99.6%, with the worst case equal 98.7%. Less than 0.05% of False Positives are detected.

Abstract: In a significant class of sensor-network applications, the identities of the reporting sensors constitute the bulk of the communicated data, whereas the message itself can be as small as a single bit—for instance, in many cases, sensors are used to detect whether and where a certain interesting condition occured, or to track incremental environmental changes at fixed locations. In such scenarios, the traditional network-protocol paradigm of separately specifying the source identity and the message in distinct fields leads to inefficient communication. This work addresses the question of how should communi- cation happen in such identity-aware sensor networks. We re- examine the traditional source-identity/message separation and propose a scheme for jointly encoding the two. We use this to develop a communication method for identity-aware sensor networks and show it to be energy efficient, simple to implement, and gracefully adaptable to scenarios frequently encountered in sensor networks—for instance, node failures, or large numbers of nodes where only few are active during each reporting round. I. INTRODUCTION In traditional network protocols, each packet carries its source identity in a dedicated header field, separately from the communicated message, which constitutes the packet's payload. To increase their information rate, several protocols use encoding or compression techniques that look to minimize the size of the message; to the best of our knowledge, none

Abstract: Method, apparatus, and computer program product embodiments are disclosed to improve power saving in wireless communication, more particularly in the Bluetooth Low Energy protocol. Conventional Bluetooth packets include a preamble used for radio synchronization, an access address used for physical link identification, a protocol data unit (PDU) to carry the data and a cyclic redundancy code (CRC) to ensure correctness of the data in the PDU. When the sending device determines that it does not have any payload data or acknowledgment to previous data to send and yet it wants to keep the communication link alive with the receiving device, the sending device takes the following steps. The sending device uses a predefined access address in the Bluetooth packet, which is different from normal Bluetooth communication. Then the sending device omits including the PDU and the CRC in the packet. At the receiving device, the presence of the predefined access address in the Bluetooth packet indicates to the receiving device to keep the communication link alive when there is no actual payload data traffic between the devices. The predefined access address serves as an indication to the receiving device to keep the connection between the devices active/alive, but to not expect any payload data from the sending device.

Abstract: A method for searching a PDCCH in a wireless communication is provided to reduce the overhead caused by blind decoding and shorten the time taken for the search of the PDCCH that a terminal requires. A terminal demaps physical resources elements into a CCE(Control Channel Elements)(S210), and demodulates a CCE aggregation level(S220). The terminal dematches the demodulated data with a transmission rate according to the correspondent payload and the CCE aggregation level(S230). The error occurrence is detected based on the CRC(Cyclic Redundancy Check) of encoded data(S240), and the terminal that detects its PDCCH(Physical Downlink Control Channel) removes the CRC from the decoded data and obtains the necessary control information(S250).
