摘　　要：本文介绍了QPSK信号产生和解调的相关原理。利用数字信号处理芯片运算速度快、可编程性能好、抗干扰能力强,能适合于实现复杂的算法的特点,结合CCS开发平台,完成了以汇编语言为基础的QPSK信号解调的DSP仿真。通过对比Matlab仿真和DSP仿真结果,验证设计的解调过程各项性能指标均达到设计的要求。The article introduces the fundamental principle of widely used codes such as Hamming codes.Based on the features of the fast rate of computation, the strong capability to resist the interference and the adaptability to realize the complicated algorithm. Associating the code composer studio,it also accomplishes the Hamming coding which is suitable for DSP based on assembly language.Through the test,various function index of the simulation software reaches the requirement of design.
