| Abstract: | This paper mainly introduces the implementation of quadrature phase shift keying（ QPSK） modem. By the design of the module of carrier and symbol synchronization and phase ambiguity correction in QPSK demodulation system,a field programmable gate array（ FPGA） hardware based QPSK modem system is proposed for realization and then it is tested in a KC705-FPGA evaluation board. The experimentation results indicate that the proposed scheme attain the anticipated goal of realizing precise modulated baseband signal recovery. |
