Layered Capacity-Based Relay-and-Antenna Joint Selection for MIMO-AF-Multiple-Relay Systems in Correlated Channels

Figure 3

System-capacity performance comparisons of various destination antenna selection algorithms in terms of SNR for an AF-MIMO multiple-relay system with [𝑁_S,𝑁_R,𝑁_D,N,K,L] = [10,2,10,10,4,4] and a fixed relay antenna-pair selection process in the (a) low and (b) high spatial-correlation channels.
