摘　　要：在高速数据传输系统中,目前用得较多的数字调制方式是相干2DPSK。阐述了2DPSK调制解调的基本原理,在MAX+PLUSⅡ软件平台上,给出了利用复杂可编程逻辑器件设计的2DPSK调制解调电路,并进行了编译和波形仿真。综合后下载到复杂可编程逻辑器件EPM7128SLC84-15中,测试结果表明,达到了预期的设计要求。Coherent 2DPSK is the commonly - used digital modulation mode in high - speed data transmission systems. This paper elaborates the principle of 2DPSK modulation and demodulation ,provides a circuit design of 2DPSK modulator and demodulator,by using the logic -unit of CPLD on the EDA software platform of MAX ＋ PLUS 1I. Editing, compiling and waveform simulation are performed. After being synthesized ,it is downloaded into the CPLD of EPM7128SLC84 - 15 for test and the result shows that the expected design requirement is met.
