To improve the anti-interference performance of communication equipments better, introduces its principle and characteristics of the frequency-hopping communication at first. Then it gives an introduction of the overall design, development language and tool of the receiving system of the frequency-hopping communication based on FPGA. At last, put forward it design of frequency-hopping receiver’s timing control. The result shows, compared to the conventional receiving system of frequency-hopping communication, the system has the advantage of better flexibility, high reliability, shorter development cycle and less cost, and it has some reference for the design of new frequency-hopping communication receiving system.
