摘要
基于Kronecker积的方法给出MIMO相关信道的建模方法,分析MIMO信道的容量及其影响因素。通过实验仿真得出多径效应在MIMO系统中的应用能够提高通信速率,增大信道容量,与OFDM技术的结合使MIMO系统很好地克服了信道中的频率选择性衰落,使系统的误码率减小,进一步提高了系统容量。
In this paper, the method of modeling MIMO-related channels is given based on the Kronecker product. The capacity of MIMO channel and its influencing factors are analyzed. The experimental results show that the application of multipath effect in MIMO system can improve the communication rate, increase the channel capacity. And the combination with OFDM technology makes the MIMO system a good way to overcome the frequency selective fading in the channel,which reduces the bit error rate, and further improve the system capacity.
