摘要：

This letter presents an efficient technique to reduce the impact of nonlinear power amplifiers on the bit error rate (BER) of orthogonal frequency division multiplexing (OFDM) systems. The proposed technique is based on the well-established Partial Transmit Sequence (PTS), a power amplifier model, and a simple single point cross correlator. Unlike the conventional PTS, the optimum phase sequence in the proposed system is selected by maximizing the correlation between the input and output of the power amplifier model. Simulation results have confirmed that the BER using the proposed technique is almost identical to the state-of-the-art while the complexity of the proposed optimization metric is significantly reduced.
