Relay selection for grouped-relay networks using the average SLNR measure
Jingon Joung, Ali H. Sayed · 2009
In this paper, a distributed grouped-relay network with multiple source and destination nodes is introduced, and its distributed beamforming based on an average signal-to-leakage-plus-noise ratio (SLNR) is proposed to mitigate interference and colored noise from the multiple relay groups. Through system bit-error-rate simulations, it is verified that the performance of the leakage-based selection scheme is comparable to a signal-to-interference-plus-noise ratio (SINR)-based optimal beamforming method albeit at much lower complexity.
