多径信道下可有效提高频偏估计性能
文章对几种常用的基于循环前缀(CP)的最大似然同步算法进行了分析,并对其频偏估计方差进行了比较;同
时针对基于CP 的同步算法在多径衰落信道下性能较差的情况,提出了一种改进的CP 同步算法并进行了仿真,结果表明相比
于原ML 算法,文中算法在多径信道下可有效提高频偏估计性能。(】This paper does some research on multiple maximum-likelihood (ML) algorithms based on cyclic prefix
(CP) and compares variances of frequency-offset estimation After the analysis of the bad performance of CP based
algorithms in multi-path fading channels, an improved CP algorithm is proposed and the simulation shows that this
algorithm can improve its performance effectively in multi-path fading channels.)
