Abstract :
In this paper, we present a new iterative phase noise mitigation method for Turbo coded OFDM system and analyze the influence of phase noise on system performance. The soft output of turbo decoder is used to estimate the phase noise in the frequency domain iteratively, and then cyclic convolution is adopted to correct the phase noise. Simulation result shows the proposed method can significantly improve system performance through some few times of iteration
