摘要:
提出了一种基于粒子群的相位优化组合算法来抑制OFDM信号的高峰平比,结合相位优化组合算法,通过寻找使峰平比最小的相位来抑制信号的高峰值信号的原理,利用粒子群算法无需过多原始信息、收敛迅速快、寻优准确等优点解决了寻找抑制OFDM信号峰平比的最优相位向量问题.实验仿真结果表明,提出的改进算法在不过多增加系统复杂度的同时,更为有效地抑制了OFDM信号的高峰平比现象.
Abstract:
As the problem of high PAPR(peak to average power ratio) in OFDM signals has greatly affected the application prospect of OFDM (orthogonal frequency division multiplexing) system, the PSO (particle swarm optimization) algorithm was applied in the phase optimization combination method for PAPR reduction, because comparing with the best algorithm proposed by Newman and Narahashi, it can search the optimization accurately with few original messages and less time, based on choosing the phasic signal approximately. The simulation result shows that the algorithm introduced in this paper is better in the same condition. Meanwhile, its computational complexity is not increased too much.
