The software method is introduced by employing DDFS technology to realize the transformation of digital signal into FFSK signal. The conventional DDFS technology is improved a lot to achieve its function on single chip micro-computer without using too much resources.

The results show that the FFSK has more virtues of phase continuation and higher band utilization than FSK and PSK/ DPSK.

结果表明：FFSK调制解调器具有相位连续、包络恒定的特征，频带利用率优于一般FSK和PSK/DPSK。
