摘要

针对峰值检测超宽带接收机,利用高斯信道下其系统误比特率是关于比较器门限的凸函数的特点,提出一种基于训练序列的动态门限控制算法.理论分析和数值仿真表明,动态门限控制算法不仅实现复杂度低,而且能够动态跟踪和快速逼近最优的比较器门限,以获得最小的系统误比特率.

Abstract

The performance of peak detection of ultra-wide band receiver is greatly affected by the threshold of the comparator. Considering that the bit error rate is a convex function of the threshold, we propose a dynamic threshold control based on training sequence. The simulation results show that the proposed practical algorithm can track and approach the optimal comparator threshold to achieve better reception performance.
