A novel non-data-aided frequency estimation algorithm for M-PSK signals

摘要：

　　This paper deals with the problem of carrier frequency estimation for MPSK symbols.We present a novel non-data-aided method by introducing a step factor into an earlier estimation algorithm to reduce the computational complexity with little loss of the estimation accuracy.We also make some comparisons with earlier algorithms.From the results of simulations,we make the conclusion that the new method can separate the estimation range and the estimation accuracy,and avoid the weakness of reaching large estimation range at the expense of estimation accuracy.
