Abstract :
This paper proposes a scheme of demultiplexing and demodulating 32-channel FDM/QPSK signals based on a DSP chip of TMS320-C6201. The results of simulating the scheme with a TMS320-C6201 developing kit suggest that the scheme is reasonable and feasible. Implementation of the scheme could provide a low-complexity solution for multi-carrier demodulation in satellite communication
