摘要
Orthogonal Frequency Division Multiplexing (OFDM) systems are susceptible to High Power Amplifier (HPA) nonlinearities because of the high Peak to Average Power Ratios (PAPR) in the symbols that are transmitted. Clipping or otherwise limiting these high peaks causes in-band and out-of-band distortion in the signals. This study focuses on clipping noise mitigation using iterative receivers based on Bussgang Noise Cancellation (BNC) and Decision-Aided Reconstruction (DAR). A modified DAR receiver is simulated with oversampled clipping and filtering. Both receivers are compared in terms of bit-error rate (BER) and number of iterations.
