Abstract: An error detection system for discrete receiver. The error detection system indicates bad frames of binary information signal which contain distorted bits in excessive numbers so great as to cause a convolutional decoder to generate an incorrect, decoded signal. A signal decoded by a convolutional decoder (512) is re-encoded by an encoder (524), and the re-encoded signal (530) is compared with the signal received (506) by the receiver. When excessive numbers of re-encoded signal portions differ too greatly with corresponding portions of an actual, received signal, a bad frame indication is generated (590).

Method and apparatus for determining data rate of transmitted variable rate data in a communications receiver
Brian K. Butler,Roberto Padovani,Ephraim Zehavi +2 more
- 26 Apr 1994
TL;DR: In this article, a system for determining the rate at which data has been encoded in the receiver of a variable-rate communications system was proposed, where the data is received in frames having a fixed number of symbols and multiple copies of symbols fill the frame when data is encoded at less than the full rate.

TL;DR: In this article, a threshold value is selected based in part on the quality metrics of received frames, which can relate to an energy of a received frame, a distance between an received frame and a codeword corresponding to the received frame or other metrics, and can be dynamically adjusted based on current information available at the receiver.

- 15 Apr 1996
TL;DR: In this paper, a variable threshold generator (440) is used to generate bad frames of binary information signals which contain distorted bits of data in numbers so great as to prevent a convolutional decoder (738) from generating, accurately, a decoded signal.

- 27 Sep 1991
TL;DR: In this article, a Viterbi decoder is used to reconstruct from the received signal an estimate of a data bit that was coded for transmission, which is then re-encoded and provided to a trellis output mapper along with the sector value.

TL;DR: In this paper, a signal weighting system for associating a confidence level with portions of a communication signal transmitted upon a multipath channel and received by a receiver is presented, where the signal received by the receiver is altered responsive to values of a filtered, equalized signal generated by the adaptive filter.

TL;DR: In the concatenated coding data compensation communication system, the coding and decoding are performed in a differential coder and a differential decoder, and the 2-channel output obtained after coding is parallel-to-serial converted and then subjected to synonym insertion before being transmitted.
