摘要
针对卫星USB测控系统中常用的DPSK-PM调制技术,设计了一种简单的数字解调方法。在介绍算法原理的基础上,对解调算法进行了仿真,仿真结果证明了该方法的有效性。该方法对于航天测控链路信息对抗仿真平台的建立具有指导意义。
A simple digital demodulation method is proposed for the DPSK-PM modulated signals, which are commonly used in the satellite USB （Unified S-band） tracking telemetry and command system. The demodulation algorithm is simulated after the principle of algorithm was introduced. Through simulation, the validity of this algorithm is proved. This algorithm has great instruetive meaning for the foundation of simulation flat for information confront of spaceflight tracking telemetry and command link.
