摘要
通过比较信道容量公式中的参数,利用行列式结合律特性和逐级递增天线数量的指导思想,提出了一种改进型快速天线选择算法.该算法与传统的快速天线选择算法相比,能够更快地选择出对信道容量贡献最大的接收或发送端天线,在不影响信道容量和系统误码率性能的情况下,可显著降低计算复杂度.
By comparing the parameters of channel capacity formula and using the method of determinant combination characteristics and gradually increasing number of antennas, this paper proposes an improved and fast antenna selection algorithm. Compared with the traditional approach to fast selecting antenna, this method is more efficient in the sense that it is able to select, in a faster manner, the received and sent antennas which are most beneficial to channel capacity. In addition, calculation is remarkably simplified in the case where the channel capacity and systematic error rate are not influenced.
