The exact expressions for symbol error probability and outage probability of randomized distributed space-time codes (RDSTC) under Rayleigh fading are derived. The diversity gain derived in the literature uses the Chernoff bound which may not be achievable in general. Utilizing the exact expression, the achievable diversity gain of RDSTCs is validated. The analytical expressions are verified by Monte-Carlo...
In this paper, performance of Transmit Antenna Selection / Maximal Ratio Combining (TAS / MRC) in two hop Amplify-and-Forward (AF) relay system is analyzed over frequency non-selective and slowly Rayleigh fading channel. In the system, all nodes are equipped with multiple antennas; TAS is employed at the source and relay for transmission, MRC is employed at the relay and destination for reception...
Cooperative communication has characteristics of spatial diversity and virtual antenna, thus it can improve communication efficiency significantly in cellular or wireless data networks. One of the essential design issues in cooperative communication is partner selection mechanism. The problem of selecting suitable partners for a cooperative strategy is more complex when prospective partners have links...
