| Abstract: | An optimal algorithm based on partial transmit sequences (PTS) for reducing the peak to average power ratio (PAPR) of orthogonal frequency division multiplexing signal is presented. Simulation result shows that these algorithm, which are less complex and more easily implemented, suffer little PAPR performance degradation. |
