Performance on Suboptimal Antenna Selection for Cooperative Cell System

Abstract

Cell antenna cooperative strategy might have more realizable, more fairness and more potential capacity than multi-user cooperative diversity. However, different from multi-user diversity, the fading of each Cell-antenna is obviously independent and non-identically distribution for any mobile user, it is hard to get an optimal scheduling strategy directly by a gen-eral closed expression. In this paper, we investigate the performance of multi-antenna selective cooperative strategy based on the cooperative Cell, the equal power transfer and the equal gain receive combining methods that are suboptimal but practical. The theoretic and Monte Carlo simulation analysis show that for the mobile node with only one antenna, the traditional handover strategy is the best one, but for the node with multi-antenna the suboptimal multi-antenna selection could improve the outage capacity obviously than the traditional cell by cell handover strategy.
