Turbo Equalization for Clipped and Filtered COFDM Signals
— Clipping and filtering is an attractive method for the reduction of the PAPR of OFDM signals before transmission. However, the resulting in-band distortion noise impacts the error rate performance. Since the optimum soft iterative equalization scheme has a prohibitively high computational complexity, we present two equalization algorithms for clipped and filtered COFDM signals with reduced complexity. The coded frame error rate (FER) performance over both AWGN and frequencyselective fading channels is evaluated for typical OFDM system parameters.
