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 Matlab software to simulate the dynamics simulation. Using simulation results, from the baseband signal waveform can be measured digital signal transmission quality by the system' s input and output waveforms can be seen that simulation is good.)

说明： In this paper, a new direction-of-arrival (DOA) estimation method based on multiple Toeplitz matrices reconstruction is proposed for coherent narrow band signals with a uniform linear array (ULA).(Even in the case of a low signal-to-noise ratio and low snapshot number with half the array aperture reduced, the new method provides good performance on estimation and resolution.)
