Abstract: Using algorithms based on CP frequency offset estimation and PSS frequency offset estimation, OFDM synchronization of LTE system is studied and the two algorithms are compared. According to the characteristics of the traditional algorithm based on CP frequency offset estimation algorithm, protection interval is selected as a quarter of the relevant window, and then is conjugate within the relevant window, finally the algorithm is improved by calculating the average value. Simulation results show that compared with the traditional CP algorithm, the performance of the improved CP algorithm reduces the mean square error by two orders of magnitude.

Key words: LTE, frequency offset estimation, CP algorithm, OFDM
