一种用CPLD实现的2DPSK调制解调器

Design and Realization of a Modem of 2DPSK Based on CPLD

给出了一种用VHDL语言设计2DPSK调制解调器的方法.详细叙述了其工作原理及设计思想,并用复杂可编程逻辑器件CPLD予以实现.另外给出了程序设计和仿真波形,介绍了调制解调器的数据传输速率和载波频率的修改方法.

A design method for a modem of 2DPSK by LHDL programming language in present. The principle and design method of the modem of 2DPSK are described in detail. According to our method, we carry out the Modem of 2DPSK based on complex programmable logic device (CPLD). In addition, the method of program design and the working wave of the modem obtained by simulator are given. The data transport rate and modulating method of carrier wave frequency of the modem are also described.
