摘要
天线选择以损失较小的性能而增加MIMO系统的信道容量,为使系统能够快速选择出一组天线使得MIMO系统的信道容量最大,本文提出了一种改进的MIMO系统天线选择算法。该算法在一次选两根天线的基础上进行改进,改进后的算法在计算信道容量时免于矩阵求逆的相关运算,经仿真验证,系统在减少计算量的同时性能变化不大。
Antenna selection reduces the performance to increase the channel capacity of MIMO systems.In order to select a group of antennas that is the largest with channel capacity of MIMO system quickly,an improved antenna selection algorithm for MIMO system is proposed.The algorithm is based on selecting two antennas one time.The improved algorithm avoids the matrix inversion when calculates the channel capacity.Computer simulation shows that the system reduces the amount of calculation with little change in performance.
