应用于窄脉冲超宽带通信的均衡算法及其实现

摘要

Due to high transmission rate and multipath effect in narrow-pulse ultra-wideband ( UWB ) communication system,the time domain equalization technology based on traditional transversal filter is un-able to deal with sever inter symbol interference(ISI). By joint design of receiver and transmitter,a fre-quency domain equalization algorithm based on data block transmission is proposed and its application pre-condition and implementation are introduced. The simulation result shows that the proposed algorithm can effectively resist inter symbol interference( ICI) in UWB communication system and it is a more realistic al-ternative for IR-UWB systems.%由于高传输速率及多径效应的影响，在窄脉冲超宽带( IR-UWB)通信系统中，基于传统横向滤波器的时域均衡技术已无法对抗严重的码间干扰。通过收发两端联合设计，提出了一种以数据块为基础的基于码元的频域均衡技术，同时介绍了其应用前提和算法实现。仿真结果表明，所提方法能有效对抗超宽带通信系统中存在的码间干扰，是窄脉冲超宽带通信系统中更为现实的技术选择。
