Space-time codes and concatenated channel codes for wireless communications
Proceedings of the IEEE, 2002 Following a brief historical perspective on channel coding, an introduction to space–time block codes is given. The various space–time codes considered are then concatenated with a range of channel codecs, such as convolutional and block-based turbo ...

Space-time network coding [PDF]
IEEE Transactions on Signal Processing, 2011 Traditional cooperative communications can improve communication reliability. However, transmissions from multiple relay nodes are challenging in practice. Single transmissions in time-division multiple-access (TDMA) manner cause large transmission delay, but simultaneous transmissions from two or more nodes using frequency-division multiple access ...

Layered Space-Time Index Coding [PDF]
IEEE Transactions on Information Theory, 2018 Multicasting $K$ independent messages via multiple-input multiple-output (MIMO) channels to multiple users where each user already has a subset of messages as side information is studied. A general framework of constructing layered space-time index coding (LSTIC) from a large class of space-time block codes (STBC), including perfect STBC, is proposed ...

Structured Dispersion Matrices From Division Algebra Codes for Space-Time Shift Keying [PDF]
, 2013 We propose a novel method of constructing Dispersion Matrices (DM) for Coherent Space-Time Shift Keying (CSTSK) relying on arbitrary PSK signal sets by exploiting codes from division algebras. We show that classic codes from Cyclic Division Algebras (CDA)

Cooperative space-time codes with network coding [PDF]
EURASIP Journal on Wireless Communications and Networking, 2012 Because of the gains like diversity, throughput, and the coverage extension provided by the multiple-input multiple-out (MIMO) systems, it has been part of the various wireless communications standards. However, to reap the benefits offered by MIMO systems in size-constrained nodes, used in wireless communications, has been a challenging issue.

Space–Time Codes From Sum-Rank Codes [PDF]
IEEE Transactions on Information Theory, 2022 Just as rank-metric or Gabidulin codes may be used to construct rate-diversity tradeoff optimal space-time codes, a recently introduced generalization for the sum-rank metric -- linearized Reed-Solomon codes -- accomplishes the same in the case of multiple fading blocks.

Multiple-Symbol Differential Sphere Detection Aided Differential Space-Time Block Codes Using QAM Constellations [PDF]
, 2011 We propose Multiple-Symbol Differential Detection (MSDD) aided Differential Space-Time Block Codes (DSTBCs) using QAM. Our solution eliminates the requirement of high-complexity MIMO channel estimation and its pilot overhead, while mitigating the ...

On the Existence of Perfect Space–Time Codes [PDF]
IEEE Transactions on Information Theory, 2009 Perfect space-time codes are codes for the coherent multiple-input multiple-output (MIMO) channel. They have been called so since they satisfy a large number of design criteria that makes their performances outmatch many other codes. In this correspondence, we discuss the existence of such codes (or more precisely, the existence of perfect codes with ...
