Performance evaluation of OFDM with the compensation technique of the nonlinear distortion using partial transmit sequence and predistortion

To improve the bit error rate (BER) performance of the linearlized constant power coded OFDM (LCP-COFDM) that is the compensating technique for the nonlinear distortion, we propose a technique that combines the partial transmit sequence (PTS) technique with the LCP-COFDM technique. By means of the computer simulation, we evaluate the BER and power spectrum density (PSD) performances of the proposed technique. In the BER performance evaluation, we consider both cases where the side information of the PTS technique is coded and uncoded by error correction codes. As a result, we show that the proposed technique can improve the BER performance, with keeping very low out-of-band emission.
