提出了一种PM/BPSK复合调制信号的数字解调算法.该算法采用全数字方法实现载波同步和位同步,从而减小了算法的复杂度,提高了运算速度.文章分别讨论了PM解相和BPSK信号的解调,重点讨论了BPSK信号的解调过程,并给出相应的仿真结果,最后对算法的性能进行了分析.
A digital demodulation algorithm of PM / BPSK composite modulation signal is proposed, which uses carrier-based synchronization and bit synchronization using all-digital method, thus reducing the complexity of the algorithm and increasing the computing speed.In this paper, And demodulation of BPSK signal, the demodulation process of BPSK signal is discussed in detail, and the corresponding simulation results are given. Finally, the performance of the algorithm is analyzed.
