Space-time block codes from cyclic design

- 04 Apr 2005

- Vol. 9, Iss: 3, pp 231-233

TL;DR: A space-time block coding scheme based on cyclic design is presented that provides full rate and full diversity for quaternary phase shift keying symbols in systems with three or four transmit antennas.

Abstract: It has been proved that full-rate complex orthogonal space-time block codes do not exist for systems with more than two transmit antennas. In this paper, we present a space-time block coding scheme based on cyclic design. The proposed codes provide full rate and full diversity for quaternary phase shift keying (QPSK) symbols in systems with three or four transmit antennas.

Multilevel Space-Time Trellis Codes for Rayleigh Fading Channels.

- 01 Jan 2008

TL;DR: A new transmission scheme is proposed, which benefits from the advantages of conventional space-time trellis codes but does not have the disadvantages, especially for larger signal constellations, and outperforms layered schemes at high SNRs, using a smaller number of antennas.

TL;DR: In this article, it is shown that MIMO systems with distributed antennas can be treated in a single, unifying framework, and this fact is utilized to develop appropriate transmit power allocation strategies for co-located and distributed multi-input multiple-output (MIMO) systems.

Transmit Antenna Shuffling for Quasi-Orthogonal Space-Time Block Codes With Linear Receivers

Yi Yu, +2 more

- 07 May 2006

TL;DR: It is demonstrated that with the linear zero-forcing and the minimum mean squared error (MMSE) receivers, the closed-loop QO-STBC of four transmit antenna shuffling patterns can achieve almost the same performance as the ideal 4-path diversity by using two feedback bits and it is about 4-5 dB better than the open loop schemes.

Hybrid ARQ Schemes for Non-orthogonal Space-time Block Codes

Rui Lin

- 01 Jan 2007

TL;DR: Simulation results reveal that, compared to using TS-ARQ with orthogonal space-time block codes (OSTBCs), using NOSTBCs with any of the three proposed HARQ schemes can provide significant gains in terms of dropped packet rate and spectral efficiency at the cost of increased decoding complexity.
