摘要
对接收天线选择算法进行了研究,通过连续选择使出多输入多输出(MIMO)系统容量增加最大的天线的方法,用矩阵及行列式运算导出了一种接收天线选择算法,并基于空时分组编码(ST-BC),利用该算法对天线选择后的MIMO系统的容量和误比特(BER)性能进行了分析和仿真。结果表明,该算法在信噪比较小时,进行天线选择后,MIMO系统具有最大的遍历性容量(ergodic ca-pacity);在BPSK调制和ML检测情况下,系统的误比特性能均明显优于无天线选择时的情况。
Receive antenna selection algorithms are studied and a novel algorithm is proposed.The proposed novel algorithm is established on some matrix and determinants computation,receiving antenna that can offer the best incremental capacity of multiple input and multiple output（MIMO） system selected successively.Based on space-time block code（STBC）,ergodic capacity and bit-error-ratio（BER） performance are analysised and simulated by using such a novel algorithm.The results show that the maxinum ergodic capacity of MIMO systems can be obtained in condition of lower signal noise ratio（SNR）,and at the same time,based on binary phase shift keying（BPSK） signal and maximum likelihood（ML） detection,BER is superior to these systems with no receive antenna.
