| Abstract: | One of the major drawbacks of orthogonal frequency division multiplexing (OFDM) is the high peak-to-average power ratio (PAPR) of the transmitted OFDM signal. Partial transmit sequence (PTS) is a kind of undistorted method to reduce the PAPR effectively but with high complexity. A sliding window based PTS factor searching method is proposed. Simulation results show that this method can obtain good trade offs between complexity and performance on PAPR reduction using PTS schemes. |
