摘　　要：利用Matlab的Simulink工具箱建立了QDPSK系统的仿真模型,详细地叙述了仿真参数的设置,给出了仿真结果,其结果与理论结果一致,充分地展示了如何用Simulink工具箱仿真通信系统。其创新之处在于与其他QDPSK系统仿真模型相比,该仿真模型简单,而且达到了预期的效果,为通信系统的仿真研究提出了一个方法。The simulation model of QDPSK communication system is built by using Matlab＇s Simulink toolbox. The simulation parameters are described in detail and some simulation results are given. It is indicated that the simulation results are identical to theoretical results. Moreover,it is better presents how the Simulink toolbox apply in communication system simulation. Innovation of the paper lies in the simulation model is very simple compared to other schemes and achieves anticipant result. Also,an approach is proposed for some communication systems.
