摘　　要：将MIMO的天线选择方法引入MIMO-OFDM系统。仿真分析了递增、递减、最大范数法等在接收天线选择中的性能,并给出接收天线选择联合信号处理算法如MRC、EGC等对系统性能的影响。仿真结果表明:接收天线选择会降低信道容量,而联合信号合并算法对信道容量有提高作用。The MIMO antenna selection method was introduced in MIMO-OFDM system. Then the performance of increment, decrement, maximum norm method and the impact of signal processing al- gorithms such as MRC, EGC on the system performance was simulated. Numerical results show that receiving antenna selection will reduce the channel capacity, and the combined signal processing algo- rithm will enhance the capacity.
