"基于Matlab的PSK系统仿真及Simulink工具应用-电信专业学位论文"

本学位论文是基于MATLAB的PSK系统仿真，利用Simulink工具包进行系统建模和仿真。Simulink是MATLAB提供的实现动态系统建模和仿真的软件包，能够让用户将精力从编程转向模型的构造，从而省去许多重复的代码编写工作。每个Simulink模块对用户而言都是透明的，用户只需知道模块的输入、输出以及功能即可，而不必关心内部实现细节。Simulink的这些特点使得它被广泛应用于通信仿真中。 本论文利用Simulink工具箱和建模优势，构建了常用的DPCM数字电话通信系统仿真模型，并对该通信系统进行了系统设计、仿真演示、结果显示以及综合性能分析。同时，该分析方法同样具有普遍意义，可推广到其他通信系统中。 关键词：Simulink；PSK通信系统；8PSK；系统仿真。 ABSTRACT This thesis is based on the simulation of PSK system using MATLAB, and Simulink is used for system modeling and simulation. Simulink is a software package provided by MATLAB for dynamic system modeling and simulation, which allows users to shift their focus from programming to model construction, thus saving a lot of repetitive code writing work. Each module of Simulink is transparent to the user, and the user only needs to know the input, output, and function of the module, without having to worry about the internal implementation details. It is because of these characteristics that Simulink is widely used in communication simulation. In this thesis, the commonly used DPCM digital telephone communication system simulation model is built and the system is designed, simulated, results displayed, and comprehensive performance analysis is conducted. The analysis method is also of general significance and can be extended to other communication systems. Keywords: Simulink; PSK communication system; 8PSK; system simulation.
