为解决正交小波包复用(OWPM)系统存在的高峰均功率比(PAPR)问题,提出一种基于人工蜂群的相位搜索方法。通过蜜蜂群体的信息交换实现快速收敛最优值,最终使得计算复杂度大幅度降低,同时有效地抑制信号峰均功率比。仿真结果表明:该方法能很好地协调 OWPM 系统的 PAPR 抑制性能和计算复杂度。

In order to resolve the problem of high peak to average power ratio (PAPR)in orthogonal wavelet packet mul-tiplexing (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.Sim-ulation results show that this method can well coordinate PAPR suppression performance and computational complexity of the OWPM system.
