Abstract :
To improve the bit error rate (BER) performance of the linearized constant power coded OFDM (LCP-COFDM),that is, the compensating technique used for nonlinear distortion, we propose a technique that combines the partial transmit sequence (PTS) technique with the LCP-COFDM technique. By means of 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, while keeping very low out-of-band emission
