| Abstract: | In order to resolve the problem of high peak to average power ratio(PAPR)in orthogonal wavelet packet multiplexing(OWPM)system, a phase search method based on artificial bee colony is proposed in this paper, which is through the information exchange of honey bee colony to achieve fast convergence of the optimal value. The new method can ultimately make a significant reduction in computational complexity, while effectively suppressing signal PAPR. Simulation results show that this method can well coordinate PAPR suppression performance and computational complexity of the OWPM system. |
