摘要
针对宽带梳状谱干扰信号存在峰均值功率比(PAPR)较高的问题,提出了一种新的包络优化法,采用了优化初相的快速搜索、优化编码图案和加扰码等技术,不失真地降低了信号的PAPR。通过理论分析和仿真试验,验证了针对某类高速跳频信号采用新方法而设计的梳状谱干扰信号,可将PAPR严格地抑制到9dB,方法简单、其适应性和可行性强。
A method for suppressing the peak to average power ratio of broadband jamming signal with comb spectrum has been introduced in the paper.The advanced techniques has been utilized such as optimized scrambling code,Golay complementary sequences and initial phase search methods,so as to obtain lower PAPR in generation of jamming signal without distortion.Simulation has been carried out and verified that signal with comb spectrum aimed at these signals can strictly suppress the PAPR without distortion to 9 dB,and this method is simple in calculation and has good adaptability and can be utilized for hardware implement of the engineering system.
