Exact Error Performance Analysis Of Binary Space-Time Block Coded Cooperative Communications Systems In Rayleigh Fading Channels, Le Chung Tran, Zixuan Lin, Farzad Safaei, Alfred Mertins, Duy T. Ngo

Faculty of Engineering and Information Sciences - Papers: Part A

Cooperative communications using the Alamouti space-time block code (STBC) has been mentioned intensively. However, to our knowledge, an in-depth error performance analysis for a space-time coded cooperative communications system, where each node acts as both a source node and a relay node for its partner, has not been reported. Intuitively, cooperative communications would not always be better than direct transmission, but only under certain conditions. This paper first derives an exact performance analysis of the Alamouti STBC cooperative communications for a Binary Phase Shift Keying (BPSK) constellation, which could be extended to a higher density modulation scheme. This mathematical analysis …
