A Method of π/4-DQPSK Modulation and Demodulation Based on FPGA

π/4-DQPSK is a linear narrowband digital modulation technology,which possesses features of high spectrum utilization ratio,strong anti-fading performance,capture-effect and anti-multipath.π/4-DQPSK can meet the requirement of modulation technique for digital mobile communication system,and it is widely used and researched in land mobile communication and digital satellite mobile communication.In this paper,a method of realizing /4-DQPSKmodulation based on FPGA is introduced.The result shows that this scheme of π/4-DQPSK is practical and feasible.
