| 摘 要： | 为在通用计算机上实现全软件化的PCM/DPSK数字信号解调,文章研究了基于数据块的基带信号处理流程和算法,以此为基础设计了PCM/DPSK信号软件化解调系统。并提出采用基于离散傅里叶变换(DFT)算法来实现PCM/DPSK信号的全软件化解调,实际应用表明采用该方法可以正确实现DPSK信号的解调,与传统的解调方法相比,不仅解调过程简单、计算量小,而且易于软件化实现。

| Abstract: | The baseband signal’s process flow and scheme based on data class to realize PCM/DPSK signal’s software demodulation on general computer are studied,and a demodulation system of PCM/DPSK signal on this research is designed.Then proposed to use a DFT(Discrete Fourier Transform)-based digital demodulation scheme for PCM/DPSK signal is proposed,the fact of applying proves this method can realize DPSK signal’s demodulation rightly.Comparing with traditional method,not only the process is simple and easy to realize with less computation,and convenient to be programmed by software. |
