- Abstract
The /4-DQPSK modulation mode is being widely attention because of its high spectrum efficiency, resistance to decline outstanding characteristic such as being strong of performance. This paper briefly introduced the working principle of the ?/4-DQPSKand baseband difference of demodulation. It makes program design based on the system, program design is presented. The paper achieves /4-DQPSK modem system. Through simulation, the modem flow of data and input data stream is the same, just modulator delay than the 2 samples. It shows that the design method is feasible and effective.
