摘    要
本文以Simulink 为软件平台，充分利用其提供的通信工具箱中的模块，以常用的DPCM(Differential Pulse Code Modulation)和PCM(Pulse-Code Modulation)数字电话通信系统为例，对这两种通信系统进行了模型构建、系统设计、参数设置、仿真演示、结果显示、误差分析以及综合性能分析，其中还包括了A律与μ律量化误差的分析，并且重点对DPCM与PCM进行误差分析和比较，并且对差错不可控以及频带利用率不高的缺点加入了纠错编码和复用技术并对其进行了仿真。通过系统的仿真与分析可以看出Simulink 在系统建模和仿真中的巨大优势，根据仿真结果分析系统性能，并且找出最优的系统配置方案。
MATLAB is a system of high degree integration. Simulink is a software package that is used for molding, simulation and analysis to the dynamic system. MATLAB/Simulink was regarded as the software platform, and the communication system toolbox and the signal processing toolbox were utilized to design digital phone communications ystem of DPCM and PCM. And then the modeled structure, designed system, shown result, analyzed error and the comprehensive analysis were given for the two communication systems based on Simulink. The error analysis, the comparison of the DPCM and PCM, the error correction coding and the multiply were emphasized at last.
