本文基于MATLAB的PSK系统仿真进行了研究。Simulink是MATLAB提供的一个动态系统建模和仿真的软件包，它能够帮助用户快速构建模型，省去了大量重复的编程工作。在Simulink中，每个模块对用户来说都是透明的，用户只需关注模块的输入、输出和功能，而不必关心模块的内部实现。因此，Simulink被广泛应用于通信系统的仿真中。 本文利用Simulink工具箱建立了基于8PSK调制的数字通信系统仿真模型。通过模型构建、系统设计、仿真演示和综合性能分析，对该通信系统进行了详细的研究。研究结果对于理解和优化PSK系统具有重要意义，并且该分析方法同样适用于其他通信系统，具有普遍意义。 关键词：Simulink；PSK通信系统；8PSK；系统仿真 Abstract: This paper is based on the simulation of PSK system using MATLAB. Simulink is a software package provided by MATLAB for system modeling and simulation, which helps users to quickly build models and save a lot of repetitive programming work. In Simulink, each module is transparent to the user, and the user only needs to focus on the input, output and function of the module, rather than the internal implementation of the module. Therefore, Simulink is widely used in the simulation of communication systems. In this paper, a simulation model of digital communication system based on 8PSK modulation is established using Simulink toolbox. Through model construction, system design, simulation demonstration and comprehensive performance analysis, a detailed study of the communication system is carried out. The research results are of great significance for understanding and optimizing PSK systems, and the analysis method is also applicable to other communication systems, which has universal significance.
