Abstract

Demodulation technology is the most critical signal processing functionality in the communication system. Using efficient digital demodulation can improve the transmission performance of communication system. This paper introduces the principle of Continuous Phase Frequency Shift Keying (CPFSK) and its demodulation. And then designs the CPFSK demodulator by using the orthogonal differential demodulation algorithm based on software defined radio. Later, the paper deals with the structure of the demodulator. Finally, the demodulator is realized on the XC6SLX25 provided by Xilinx. The result confirms the feasibility of the all-digital CPFSK demodulator.
