Performance Analysis of Transmit Antenna Selection with Imperfect Feedback
非理想反馈链路下的发送天线选择系统性能分析

The performance of Transmit Antenna Selection(TAS)with imperfect feedback is analysed in this paper.An asymptotic method is presented to approach the Symbol Error Probability(SEP)of TAS with imperfect feedback.This method can be applied to arbitrary Orthogonal Space Time Block Code(OSTBC)scheme with TAS,and the generalized formula of SEP is also presented for Alamouti TAS scheme with imperfect feedback.It is concluded that the transmit diversity order is equal to the largest norm-amplitude ordinal number of the antenna within the selected antenna subset.It is validated by Monte-Carlo simulation that the presented asymptotic SEP match well with the theoretical SEP at high SNR.
