A Simplified Code Aided Carrier Frequency-off set Estimation Algorithm

摘要：

　　The EM algorithm in low SNR systems employs optimal search to perform the carrier frequency-offsets ML estimation,and involves high complexly.In this paper,the Three-Line-Interpolation (TLE) algorithm with high frequency offset estimation precision is replaced by the optimal search algorithm.And a simplified algorithm is proposed.The simulation results show that the computation complexity is greatly reduced and the accuracy is improved by using the TLE algorithm.And the simplified algorithm exchanges little performance loss for high computational complexity.
