摘　　要：数传已经成为测控通信系统中重要的组成部分,而影响数传解调性能的众多因素中,相位噪声是其中重要的一项。文章首先给出了相位噪声的理论分析模型,在此基础上分析了相位噪声对测控通信系统中几种典型调制方式的影响,并通过仿真对理论分析进行了验证,最后针对工程应用提出了相噪指标设计参考。Data transmission is becoming an important part of TT＆amp;C and communication systems,and phase noise is one of the most important factors that affect demodulation performance. An academic model of phase noise is introduced, the effect of phase noise on several typical modulation methods for TT＆amp;C and communication systems is analyzed,theory analysis is validated through simulation,and phase noise design reference on engineering application is proposed.
