A frequency offset estimation algorithm for multi-path fading channel based on PN sequence

A frequency offset estimation algorithm based on relativity of time-domain PN sequence is proposed in this paper. The form of this algorithm under multi-path fading channel is also given. The performance of the algorithm using different parameters is studied through theoretical analysis and simulation. The high performance of this algorithm using under both AWGN channel and multi-path fading channel is also verified by simulation.
