摘要

基于无线移动通信OFDM系统信道估计

提出了三种时域自适应特征参数估计最小均方盲方法——时变步长最小均方法(tvcpblms)、时变步长软判决最小均方法(tvcpsdwlms)、时变步长理想判决最小均方法(tvcpidwlms).这些方法通过对常规LMS算法步长进行自适应的科学设计以便跟踪特征参数变化

从而解决了常规LMS盲方法收敛速度慢、估计性能不高等缺点.仿真证明:对于不同的时延扩展、时间以及多普勒频移

这些方法均表现出了比常规方法更优的估计性能.同时

这些方法不仅可以估计无线移动通信系统信道特征参数

而且还可用于雷达、航天等多种领域估计其他特征参数.

Abstract

Three time-domain adaptive schemes including time-variance convergence parameter blind LMS(TVCPBLMS)

time-variance convergence parameter soft decision weight blind LMS(TVCPBLMS) and time-variance convergence parameter ideal decision weight blind LMS(TVCPBLMS) based on wireless mobile communication OFDM systems for channel estimation are proposed.These novel schemes could trace adaptively the channel characteristic through time-variance convergence parameter and decision weight.Simulation showed that the novel schemes had better performances with high accuracy and fast converges than those of the blind LMS method

especially via different time delay spread

time and Doppler frequency.Furthermore

these schemes are not only suitable in wireless mobile communication systems to estimation channel characteristic but also suitable in radar and spaceflight to estimation the other characteristic parameters.
