摘要
Abstract
A robust blind synchronization method for OFDM is proposed which is based on the LS blind synchronization algorithm.Firstly,the sampling period is taken as M times of the original algorithm to calculate the decision function value at the sampling points,and then the moving averages of adjacent decision function values are calculated.The timing point is the intermediate position between the two sampling points where the moving average is the minimum.The simulation results show that the proposed method not only reduces the amount of calculation,but also improves significantly the timing and frequency offset estimation performance in complicated multipath fading channels.关键词
