Digital Realization of DPSK Modem Based on FPGA

With the development of the digital technology,digital modulation and demodulation technology is being used widely.With the development of software radio,the design method integrating whole system into one chip shows us great potential.Based on this idea,the paper introduces us a digital DPSK modem realized on one FPGA chip.Based on the platform of Quartus II(ALTERA),the whole design adopts CYCLONE series of FPGA chips.
