摘　　要：文章通过对MIMO_OFDM系统信道特性进行分析,介绍了一种基于频移最小化的天线选择算法。该算法结合PN序列及奇异值分解(SVD)算法特性,在信道容量方面性能接近最佳天线选择算法,在对抗多普勒频移产生的误码率方面更优于最佳天线选择算法。This paper analyzes the feature of the MIMO OFDM system channel, and proposes an antenna selection algorithm which is based on minimizing the Doppler frequency drift. This algorithm integrates the advantages of PN sequence and the Singular Value Decomposition （SVD）. Its channel capacity performance is closed to the optimal antenna selection algorithm, and its performance of decreasing the Bit Error Rate reduction （BER） produced by Doppler drift is better than optimal antenna selection algorithm.
