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...

Reduced ML-Decoding Complexity, Full-Rate STBCs for $2^a$ Transmit Antenna Systems
— For an nt transmit, nr receive antenna system (nt × nr system), a full-rate space time block code (STBC) transmits nmin = min(nt, nr) complex symbols per channel use and in ge...

On detecting pollution attacks in inter-session network coding
Abstract—Dealing with pollution attacks in inter-session network coding is challenging due to the fact that sources, in addition to intermediate nodes, can be malicious. In this ...
