Abstract: Modern communication systems require long communication distances, large communication capacities, and good transmission quality. As one of its key technologiesModulation and demodulationTechnology has always been an important direction of research for people. This article discusses and simulates the implementation of FPGA based digitizationDPSK demodulationSystem. A simulation of a DPSK demodulation system model for baseband signals was implemented using Altera's FPGA development platform Quartus II.
