| 摘 要： | 通过选择性最大比合并(SC/MRC)算法,在并行干扰抵消(PIC)技术的基础上,对V-BLAST系统各接收天线的干扰抵消结果按照SC/MRC合并,实现了分集接收.该算法最多可以实现与接收天线数等同的分集增益,而通过选择信道条件较好的几个接收天线进行合并,可以在性能与复杂度之间取得折衷.MRC合并只需与选择合并的天线数线...

| Abstract: | The selection combining/maximal ratio combining(SC/MRC) algorithm is introduced into V-BLAST system based on parallel interference cancellation(PIC),where the cancellation residuals signal at each receiving antenna are combined by SC/MRC,so that diversity reception is achieved.The diversity gain of as much as the number of receiving antennas is obtained by the scheme,and the ratio of performance to complexity can be arrived at by selecting the receiving antennas with better channel transfer characteristics ... |
