Jointly optimized design of distributed RS-coded spatial modulation by appropriate selection at the relay

EURASIP Journal on Wireless Communications and Networking, 2023
This paper proposes the distributed Reed–Solomon (RS)-coded spatial modulation (DRSC-SM) scheme over quasi-static Rayleigh fading channel. Two different RS codes are used, one having a smaller minimum distance at the source and the other having a larger ...

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.

Cooperative Gradient Coding

IEEE Transactions on Communications
This work studies gradient coding (GC) in the context of distributed training problems with unreliable communication. We propose cooperative GC (CoGC), a novel gradient-sharing-based GC framework that leverages cooperative communication among clients.
