| Abstract: | 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. |
