A Rotated Quasi-Orthogonal Space-Time Block Code for Asynchronous Cooperative Diversity
Entropy, 2012 The rotated quasi-orthogonal space-time block code (RQSTBC) for asynchronous cooperative diversity is proposed in this paper. The source selects half of the symbols from a signal constellation set and the other half of them from that constellation ...

FULL-RATE SPACE-TIME BLOCK CODE FOR FOUR TRANSMIT ANTENNAS WITH LINEAR DECODING
Jordanian Journal of Computers and Information Technology, 2020 This paper proposes a new full-rate space-time block code for MIMO systems at four transmit antennas, which aims at minimizing the bit error rate with low-complexity decoding using ZF and MMSE linear detection techniques in Rayleigh fading channels ...

Sub-Block Rearranged Staircase Codes [PDF]
arXiv, 2022 We propose a new family of spatially coupled product codes, called sub-block rearranged staircase (SR-staircase) codes. Each code block of SR-staircase codes is obtained by encoding rearranged preceding code blocks and new information block, where the rearrangement involves sub-blocks decomposition and transposition.

An Efficient Differential MIMO-OFDM Scheme with Coordinate Interleaving
EURASIP Journal on Wireless Communications and Networking, 2007 We propose a concatenated trellis code (TC) and coordinate interleaved differential space-time block code (STBC) for OFDM. The coordinate interleaver, provides signal space diversity and improves the codeword error rate (CER) performance of the system in

Polarization-Adjusted Convolutional (PAC) Codes as a Concatenation of Inner Cyclic and Outer Polar- and Reed-Muller-like Codes [PDF]
arXiv, 2023 Polarization-adjusted convolutional (PAC) codes are a new family of linear block codes that can perform close to the theoretical bounds in the short block-length regime. These codes combine polar coding and convolutional coding. In this study, we show that PAC codes are equivalent to a new class of codes consisting of inner cyclic codes and outer polar-

Code diversity in multiple antenna wireless communication
, 2008 The standard approach to the design of individual space-time codes is based on optimizing diversity and coding gains. This geometric approach leads to remarkable examples, such as perfect space-time block codes, for which the complexity of Maximum ...
