摘要
为满足未来人们对移动通信越来越高的要求,实现真正意义上的通信无所不在,通信系统为用户提供更高速率的数据业务和更好的用户体验,已成为当今移动通信发展的趋势,而准确的信道估计算法恰恰是保证无线移动通信系统良好性能的关键所在。介绍了无线移动通信系统中信道估计基本概念,和无线移动通信系统常见的信道估计算法,重点介绍了基于多普勒频移的信道估计算法。
In order to meet the increasing demands of mobile communication in the futwure and become ubiqui-tous in our daily life,it has become the trend of mobile communication development that communication systems provide users with higher-speed data services and better user experience nowadays,while accurate channel esti-mation algorithms is the key to ensure good performance of wireless mobile communication systerms.This paper first-ly introduces the basie concept of channel estimation in wireless mobile communication systems,secondly presents the channel estimation algorithm commonly used in wireless mobile communication systems,and finally recommends the channel estimation algorithm based on Doppler frequency shif.
