摘　　要：提出了一种用FPGA解调来提高紫外通信系统的传输速率的方法;采用FPGA设计解调电路,很好地处理了2FSK信号的过渡带问题,使传输的信息经调制后能正确解调;在传输速率为9.6 kb it/s时,误码率仅为0.001%,数据速率已经达到了国际先进水平。Transmission rate of ultraviolet communication system has been enhanced by using a kind of demodulation method with FPGA,with the method which has properly solved the transition area problems of 2FSK signals,we have properly demodulated original signal from a modulated signal. When the transmission rate comes to 9.6 kbit/s, BER is only 0. 001%. The data rate has already achieved the advanced level of the world.
