Limiting Behavior of Receive Antennae Selection
In this paper, the authors investigate the limiting behavior of receive antenna selection in Single-Input Multiple-Output (SIMO) wireless systems when the number of receive antennas gets very large. Using results on the convergence of the trimmed mean, they show that mutual information converges in distribution to the logarithm of a folded Gaussian distribution in the limit of a large number of receive antennas. The convergent distribution also shows there is channel hardening in this scenario like SIMO maximum ratio combining. For finite number of receive antennas, N, they derive the exact outage probability for SIMO with selecting the best S receive antennas.
