摘　　要：数据通信的发展 ,对相应的传输设备提出了更高要求 ,尤其是速度方面。DSP的运算速度快的优点正好能满足FSK调制解调器在速度方面的要求。本文通过对FSK调制与解调原理的分析 ,提出了用DSP实现FSK调制与解调的方法 ,重点讨论该方法的软件设计。通过实验证明 ,本方法设计的FSK调制解调器具有调制相位连续、解调无相位抖动。With the fast development of data communication, it demands much of the transmission equipments on such aspects as speed、efficiency and reliability, especially on the aspect of the speed. This thesis puts forward the method of applying DSP to achieve FSK modulation and demodulation through theory analysis of the FSK modulation and demodulation,then puts more emphasis on the software design. It has been successfully proved by experiments that FSK modem designed by this method has the characteristics of continuous phase modulation,precision demodulation and the fast transmission speed.
