摘要
合成干扰信号的峰均比对发射机发射信号功率有较大的影响,直接关系到干扰效果的优劣。因此在有多路干扰合信号合成时,分析其峰均比的分布以及如何降低峰均比至关重要。文中用互补累计概率分布函数分析峰均比的特性,用峰值截断法和随机相位叠加法来降低合成信号峰均比。
The PAR of synthesized jamming signal has great influence on the power of emitted jamming signal which is related to the jamming effect. It is necessary to analyze PAR of the synthesized jamming signal. In this arti- cle CCDF is used to describe the features of PAR and the peak-cut method and random-phase synthesis are used to decrease the PAR.
