摘要
在数字通信系统中,DMPSK解调包括常用的DQPSK和DBPSK的两种方式,本文首先分析了DMPSK直扩中频全数字解调的基本原理及系统组成,然后对解调算法和载波同步算法进行了理论分析,最后通过仿真说明该算法的可行性。
DMPSK demodulation includes two common patterns of DQPSK and DBPSK in digital communication system. Firstly, basic principle and system composition of DMPSK DSSS IF full digital demodulation system is analyzed; then demodulation algorithm and carrier synchronization algorithm are analyzed theoretically; and finally, the simulation results indicate feasibility of the algorithm.
