Abstract

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.
