A new partial transmit sequence (PTS) scheme that uses the amount of OFDM signal's nonlinear distortion to be caused by high power amplifier (HPA) is proposed. However, since it may not be practical to know in prior the exact characteristics of HPA, a new measure which is called adaptive nonlinear estimator (ANE), is achieved to estimate OFDM signals after the nonlinear HPA by applying gradient algorithm. According to combining ANE and iterative PTS (I-PTS) with simple subblock combining method, the proposed scheme can transmit the OFDM signal with minimum nonlinear distortion among OFDM signal candidates. From the results, it can be seen that a proposed scheme based-iterative PTS can achieve better performance with lower computational complexity when compared to that of conventional PTS.
