A novel wide dynamic range digital PSK demodulation

摘要

An all digital wide dynamic range PSK receiver has been designed and implemented by using field programmable gate array (FPGA) for burst communication applications in an environment with a large frequency offset. The receiver employs the differential detection to increase the receiver's robustness to Doppler shift and the sub-sampling technique with 1-bit A/D converter at the front to enhance dynamic range and reduce the complexity. The receiver has more then 70 dB dynamic range with 10Mbps bit rate in a millimeter wave communication system.
