时变信道下 OFDM 系统载波频偏估计算法研究
The Carrier Frequency Offset Estimation Algorithm for the OFDM System over the Time-varying Multipath Channel
摘要
Abstract
It summarized the principles and steps of existing typical carrier frequency offset ( CFO) esti-mation algorithms over time-varying frequency-selective channels in the OFDM system , compared these algorithms through simulation of the CFO estimation performance , and analyzed their advantages and dis-advantages .The research provides a useful reference for further studies of frequency synchronization in future.关键词
