一种用于OFDM符号定时跟踪的盲估计算法
A Blind Estimation of Symbol Timing Tracking Algorithm for OFDM
-
摘要: 利用具有循环前缀和循环后缀的OFDM帧结构，该文提出了一种新的符号定时跟踪盲估计算法。理论分析及仿真表明，无论在AWGN还是多径衰落信道条件下，该定时算法估计的均方差都小于ML算法。Abstract: A new blind symbol timing-tracking algorithm is proposed, using the special OFDM frame structure with cyclic prefix and cyclic postfix. Analysis and simulation results show that the mean square error of timing offset estimation for proposed method is superior to that of Maximum Likelihood (ML) method.
