In this paper,a full-digitized demodulation method for 2~M channel FDMA/QPSK (SCPC/QPSK) signals is Presented. With the characteristics of channel forming and modulation mode, a simplified equivalent Ployphase-FFT demultiplexer is formed by combining the direct and the conventional ployphase-FFT demultiplexing method. Furthermore, the Outputs of the demultiplexer are directly fed to a digitized demodulator so that a full-digitized integral multi-carrier demodulator is realized. This system is characterized by its simplicity in software and hardware structure,low cast computationally and convenience in real-time DSP realization. Computer simulation experiment of an integral demodulator for a 32-channel FDMA/QPSK signal suggests that the method is feasible,where some key techniques have been implemented in real-time with a TMS320C6201 DSP emulator.
