摘要

针对UWB-PPM多径信号下加权非相干接收机的误码性能表达式及相应的加权系数组合进行了推导

在此基础上通过计算机仿真对加权非相干接收机的有效性进行了验证

对子积分区间宽度及定时误差的影响进行了数值分析。结果表明

加权非相干接收机在理想情况下具有至少3dB以上的性能提升

并对子积分区间及定时误差的影响具有一定的强健容忍能力。

Abstract

The BER performance expressions and weighting coefficients of the weighted non-coherent receiver for the UWB-PPM signal were analytically derived.Subsequently

the analytical results were validated via Monte-Carlo simula-tion

and the impacts of the sub-interval width and the timing error were also numerical analyzed.It is illustrated that the weighted receiver is at least 3dB superior to the conventional non-coherent receiver

and is robust to the variations of sub-integration width and the timing error.
