摘要

针对IEEE 802.15.3a信道下UWB非相干接收机的平均误码率计算问题

基于簇生点过程模型给出了一种新的求解方法。该方法通过推导接收窗口内信噪比的均值和方差的闭合表达式

分别以高斯分布和对数正态分布近似其概率分布

给出计算UWB能量检测系统平均误码率的闭合表达式。对比分析对数正态分布、高斯分布与真实分布之间的数字特征

对数正态分布近似效果的合理性好于高斯分布近似。对比基于OOK和PPM 2种调制方式的平均误码率指标

实验结果表明对数正态分布近似效果的有效性要好于高斯分布近似。

Abstract

A novel method based on clustered point process was proposed to calculate average bit error probability（ABEP） of UWB non-coherent system on IEEE 802.15.3a channel.In particular

the expectation and variance of the sig-nal to noise ratio（SNR） in the detection window were derived in closed form.Moreover

lognormal and normal variants were employed and compared to approximate the SNR in receiver window with respects to several characteristics.The results show that lognormal approximation is more feasible than normal approximation.In term of performance with PPM and OOK modulations

the efficiency of lognormal approximation is respectively much better than that of normal approximation.
