摘要
该文首先分析了多天线系统的信道容量,然后研究了当信道矩阵非满秩时,选择发射和接收天线对信道容量的影响。仿真试验结果表明,发射天线选择能提高系统容量,同时选择发射和接收天线虽然减小了复杂度和硬件成本,但对系统容量的增加低于单独进行发射天线选择时的情况。
In this paper the channel capacity in MIMO system is introduced, then the effects of antenna selection in the transmitter and receiver on channel capacity are analyzed. Simulation results indicate that the transmit antenna selection can increase channel capacity, the selection of the receiver and transmitter antennas simultaneously can reduce complexity, but cannot improve the channel capacity.
