摘　　要：数字与模拟信号的调制解调是通信系统的核心。随着目前DSP芯片的广泛应用,用软件来实现数字信号的调制解调将变得更加方便快捷,设备的微型化集成化也更容易达到。为了设计出一种适合无线传输的基带调制解调单元(模块),以TMS320C54x DSP芯片为基础,对QPSK调制解调的DSP算法进行了研究,重点讨论软件设计,并通过仿真证明该算法能够完成QPSK调制解调的全部功能。The modem of analog and digital signal is the center of communication system. Developing with the DSP, it is more easily to achieve digital signal’s modem and the machine is more subminiature and compositive. In order to design a baseband modem for wireless digital transmitting, this paper discusses and designs a method of QPSK based on TMSC54x DSP and proves it by emluator. This paper’s emphasis is the software.
