摘　　要：针对某通信系统中的无线数传机,采用半实物仿真技术对其进行仿真,论述了基于DSP和U SB仿真单体的设计,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对数据进行处理而实现。同时给出了硬件接口设计思路和架构,最后介绍了固件的软件框架。The technique of semi kinds of communication system, the physical design o simulation is used to simulate the wireless data set in some f simulation unit based on DSP and USB is discussed; the composition and operational principle of each part of 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 sampled data. Then, the design of hardware interface is introduced; finally, the design of firmware used in USB is described.
