Differential diversity-embedding space-time block coding for 2 and 4 transmit antennas
Diversity-Embedding Space-Time Block Coding (DE-STBC), introduced in [1], enables Unequal Error Protection (UEP) using multiple transmit antennas. Even though these codes do not re...

Relay Assisted Cooperative OSTBC Communication with SNR Imbalance and Channel Estimation Errors
In this paper, a two-hop relay assisted cooperative Orthogonal Space-Time Block Codes (OSTBC) transmission scheme is considered for the downlink communication of a cellular system,...

Multigroup-Decodable STBCs from Clifford Algebras
A Space-Time Block Code (STBC) in K symbols (variables) is called g-group decodable STBC if its maximumlikelihood decoding metric can be written as a sum of g terms such that each ...

High-rate, Multi-Symbol-Decodable STBCs from Clifford Algebras
It is well known that Space-Time Block Codes (STBCs) obtained from Orthogonal Designs (ODs) are singlesymbol-decodable (SSD) and from Quasi-Orthogonal Designs (QODs) are double-sy...
