Abstract

Aiming at multi-channel IF signal processing requirements, the paper designed and implemented a multi-channel digital down-converter. Based on functional requirements and technical indexes, the implementation structure of multi-channel digital down-converter was designed and overall functional diagram was given. Functions and constitutes of each module within FPGA were described in detail. The test on function and performance of multi-channel digital down-converter system was conducted. Test method, flow and test result analysis were performed in sequence. After strict test, result shows that the digital down-converter can ensure normal and stable working of system, which can also achieve appropriate indexes.
