Capacity Degradation of Representative Antenna Selection Algorithms and an Antenna Selection Scheme
In this paper, we concentrated on investigating the performance of some representative antenna selection algorithms, and attributed the channel capacity degradation of these algorithms to two aspects: The idealized assumption or underutilization of the channel matrix for computational convenient purpose and, the local searching strategy that existing in almost all the suboptimal antenna selection algorithms. Based on these analysis, we introduced a joint antenna selection scheme, which can slightly improve the performances of the existing suboptimal algorithms by searching the local optimal of the selection result of the suboptimal antenna selection algorithm.
