摘要：
In this paper, an improved algorithm of coarse synchronization in the downlink of 3GPP LTE system is presented. This new algorithm can reduce the MSE (mean square error) of detected fractional carrier frequency offset (FCFO) by an order of magnitude and improve the accuracy rate of start point estimation by near 80 percent when SNR equals 0 in contrast with conventional coarse synchronization algorithms, such as ML, MMSE, S&C and MC. The simulation result for the proposed algorithm is presented in comparison with the conventional algorithms.
