一种降低多载波干扰信号峰均功率比的改进算法
An Improved Algorithm for Reducing peak-to-Average Power Ratio of Multi-carrier Jamming Signal
摘要
Abstract
From the viewpoint of optimization phase, the simulation results show that the PAPR of PCM, BPSK modulation signal can be effectively reduced by the Newman phase optimization method. For MPSK(M>2),QAM and other modulation signal, Newman phase optimization method can not effectively reduce the PAPR. In this paper, a method for reducing PAPR based on Newman phase optimization method combined with peak cancellation algorithm is proposed. Simulations show that this method can effectively inhibit the PAPR of multi-carrier jamming signal and can reduce the complexity of the system.关键词
