摘要
介绍了一种中频数字接收机的设计,该接收机采用AD9238实现数据采集,利用FPGA实现数字接收预处理,后续采用DSP完成相应信号处理算法。给出了系统硬件电路设计的具体方案,并对各部分硬件电路设计进行了阐述。对FPGA内部功能模块设计与实现进行了详细阐述,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,具有较高的通用性和实用价值。
A design of intermediate frequency digital receiver is introduced in the paper.The AD9238 is used to collect data and FPGA is used to realize data preprocessing and the DSP is used to complete signal processing algorithm in the digital receiver.The scheme of system realization is proposed and the design of every hardware circuit is described in detail.The design and implementation of every main function module in FPGA of the system is described with carefully.On condition of no varying hardware platform,the system can realize different function and technical index by changing software program and have higher universality and practical value.
