The design technique of FPGA related to ss communicationsystem has been discussed in this thesis. Especially, the strict synchronous which is important in FPGA design has been discussed.
In the communicationsystem, synchronoussystem function's lower will cause communication system function to lower, even making the communication system can't work normally.
在同步通信系统中，同步系统性能的降低会导致通信系统性能的降低，甚至使通信系统不能正常工作。
