设计了差分编码移相键控(2DPSK)调制解调系统的工作流程图,并利用 Matlab 软件对该系统的动态进行了模拟仿真。利用仿真的结果,从基带信号的波形图可以衡量数字信号的传输质量 由系统的输入和输出波形图可以看出,仿真实验良好 。-Design of a differential phase shift keying encoding (2DPSK) modulation and demodulation system working flow chart of the system using

First, when the inter-user distance d is small, the SNR for D2D communication is high, and hence there are sufficient number of bits for high quality CSI exchange.
