摘　　要：介绍了一种运用DSP技术来实现维特比 (Viterbi)译码器的方法。其中介绍了维特比译码器的原理及算法 ,及维特比译码器实现的过程。算法用C语言来编写 ,并成功地将其移植到DSP的集成开发环境CCS中。在此基础上 ,给出了硬件的仿真结果。由仿真测试结果表明 。This paper introduced a method using DSP technology to realize the Viterbi decoder. In this paper, the principle of Viterbi decoder realization is introduced. The approach, which is compiled using C language, is successfully transplanted into the integrated development environment CCS of DSP. On this foundation, the simulation result of hardware is obtained. Analyzing the result of simulation indicates that the system can decode accurately and rapidly.
