Combined with a concrete program,this paper analyzes and designs multi-way digital down conversion(DDC) under valid resources in FPGA.The multi-way DDC' results are combined into 8 ways by using beam forming technique.These results are finally sent to the FPGA in back board through optical fiber.The essence of this paper is to analyze and design the multi-way FIR filter by using the structure of RAM which saves a great deal of register resources.At the same time,optical fiber communication module is studied and devised,which solves the data transmission bottleneck and implements high-speed and real-time transmission.At the end,the overall simulation analysis is given,which indicates that this system is feasible and stable.
