Description: Simulink是MATLAB最重要的组件之一，它提供一个动态系统建模、仿真和综合分析的集成环境。在该环境中，无需大量书写程序，而只需要通过简单直观的鼠标操作，就可构造出复杂的系统。Simulink具有适应面广、结构和流程清晰及仿真精细、贴近实际、效率高、灵活等优点，并基于以上优点Simulink已被广泛应用于控制理论和数字信号处理的复杂仿真和设计。同时有大量的第三方软件和硬件可应用于或被要求应用于Simulink。-Abstract: In the development of communication technology, communication system simulation technology is a technical focus. This paper will focus on simulation of communication systems in the modem system and the basic principles of anti-noise performance and MATLAB simulation software platform to achieve some common analog modulation. The most important of the most commonly used analog modulation is the sine wave as a carrier perspective modulation and amplitude modulation. Common AM (AM), with bilateral (DSB), residual sideband (VSB) and single sideband (SSB) modulation,
