一种用于传播通信的新的FSK解调方法
This paper analyses the FSK modem method of fax communication.Put forward a new FSK demodulation method which uses the flexible software realization to overcome the shortcomings of the hardware realization such as higher cost.The new method can avoid the phase not synchronized problem without taking into account the phase information during demodulation.It introduces the Goertzel algorithm to save storage space and allowes to use the sampling window of arbitrary length.It is verified the effectiveness by the test result.It is used in the CDMA2000 base station system for fax services.
