摘　　要：DQPSK调制具有频谱性能好,抗频偏能力强等优点,在数据链上得到了广泛的应用。本文对DQPSK数字调制和基带差分解调技术进行了研究,并用Matlabsimulink工具进行了仿真验证,仿真结果表明,DQPSK调制能够满足高动态环境下数据链的通信需求,误码率满足技术要求。DQPSK modulation has the advantages of good spectrum performance and strong anti-frequency deviation ability,and has been widely used in data chain. DQPSK digital modulation and baseband differential demodulation are studied in this paper, and the simulation in verified by matlab Simulink. Simulation results show that DQPSK modulation can meet the communication requirements of data link in high dynamic environment, and the bit error rate can meet the technical requirements.
