摘　　要：针对某通信系统中的有线通信模块,采用半实物仿真技术对其进行仿真,论述了基于DSP和USB技术的设计,详细地描述了系统各部分的构成及工作原理,其调制部分通过按位分析数据并控制8253输出不同频率的方波实现;解调部分通过AD采样并由DSP对数据进行信号处理而实现。同时给出硬件接口设计思路和原理图,最后介绍相关软件基本框架。The technique of semi-physical simulation is used to simulate the wire communition module in a certain communication system. The design of simulation module is based on DSP and USB technique. The composition and operational principle of each part of the system are described detailedly. The modulation unit is realized by analyzing every bit of data and controlling 82C53 to send square waves of different frequency; the demodulation unit is realized by processing the AD sampled data. Second, the design of hardware interface is introduced. Finally, the design of software is described.
