用Matlab/Simulink研究2ASK(DPSK)在加性高斯白噪声信道下的误码率性能与信噪比之间的关系；试用Matlab/Simulink研究2ASK(DPSK)+信道编码（取汉明码）在加性高斯白噪声信道下的误码率性能与信噪比之间的关系-Matlab/Simulink additive white Gaussian noise channel 2ASK (DPSK) the relationship between performance and signal-to-noise ratio

基于matlab/simulink的系统仿真，有psk和dpsk的系统仿真框图-Based on matlab/simulink system simulation, system simulation there is a block diagram psk and dpsk

This Paper is concerned with the study of the performance of DPSK (differential phase shift keying) Modulation Technique using AWGN(Additive white gaussian noise) channel. The DPSK has remarkable features such as limited bandwidth and constant en
