基于FPGA的调制，实现了QPSK调制，所用芯片为Artera的CycloneIIEp2C5T114C8...

说明：  基于FPGA的用verilog语言写的，改程序可产生不同调制系数和不同频率的AM波，长按按键切换调制度25 、50 、75 和短按按键切换调制信号频率1k、1.5k、2k、2.5k.(Based on the FPGA using verilog language, change the program can produce different coefficients and different frequency modulated AM wave, long press the button to switch the modulation of 25 , 50 , 75 and short press button to switch the modulation signal frequency 1k, 1.5k, 2k, 2.5k.)
