摘要
介绍了一种基于AD9430的数字接收机的设计,给出了系统实现的具体方案,并对各部分硬件电路的设计进行了阐述.对FPGA内部各主要功能模块设计做了详细介绍,给出了各功能模块的具体实现结果,并通过仿真验证了各功能模块的正确性.该系统可以在硬件平台不变的情况下,通过改变软件程序实现不同功能和技术指标的系统,具有较高的通用性和实用价值.
A design of intermediate frequency digital receiver based on AD9430 is introduced. The scheme of system realization is proposed and the design of every hardware circuit is described. Every main function module in FPGA of the system is described and the implementation result of every module is given. The correctness of every main function module is verified by simulation. Under the condition of not varying hardware platform, the system can realize different functions and technical indexes by changing software program, so it has higher universality and practical value.
