摘要 采用分段加权合并的思想,提出了一种新的加权的UWB-ATR接收机,根据接收信号中的多径分布给予各段不同权重,有效压制了噪声乘积项,权重系数由MMSE估计得出。经过理论分析和IEEE CM3多径信道仿真,结果表明该接收机的误码率性能优于一般ATR接收机。 By using the idea of dividing-weighting-combining, a new weighted UWB-ATR receiver is presented. The receiver gives the subsections different weights according to the multipath distribution of a received signal, so noise-on-noise term is efficiently suppressed. The weight factors are obtained by using MMSE estimation. This receiver was analyzed in theory and simulated in IEEE CM3 multipath channel and the results show that it has a better bit-error-ratio performance compared with a conventional ATR receiver.
