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。
A new weighted UWB-ATR receiver is proposed based on the idea of piecewise weighting and combining, which gives different weight to each segment according to the multipath distribution in the received signal, effectively suppressing the noise multiplication term. The weight coefficient is estimated by MMSE . After theoretical analysis and IEEE CM3 multipath channel simulation, the results show that the BER performance of the receiver is better than the average ATR receiver.
