2fsk调制解调器的DSP实现，对于 2FSK，调制就是把输入数字序列变成适合于信道传输的变频正弦波（2FSK 信号）-2fsk modem DSP implementation, for 2FSK, modulation is to enter a number sequence into a suitable transmission channel frequency sine wave (2FSK signal)

FSK信号调制，是我的课程设计，程序已运行过，无任何问题-FSK signai!

Thus PSK systems require less transmitted power for a given probability of error than ASK or FSK systems. Synchronous detection of PSK signals is required,due to the absense of a large carrier component.Carrier recovery is there for emore compl
