deep learning一般是学习的层次结构，它也是有一定理论依据的，即模拟人脑的大脑皮层工作，因为大脑皮层的视觉区域也是分层次工作的，越底层的视觉皮层对那些底层特征就越敏感。综上所述，feature learning有这么多应用需求的驱动和生物神经理论上的支持，注定它能够在AI领域中发挥一定的作用。一些实验表明，有些feature learning学习到的特征几乎比所有其它的特征效果要好，比如本文中的ISA模型就是其中一个。(deep learning hierarchy of learning, it is also a certain theoretical basis that simulate the human brain' s cerebral cortex, visual areas of the cerebral cortex is hierarchical work, the more the bottom of the visual cortex is more sensitive to those underlying characteristics . In summary, feature learning so many application needs the support of the drive and biological neural theoretically doomed it to be able to play a certain role in the field of AI. Some experiments show that some feature learning learning to feature almost better than all the other features of the effect of the ISA model such as this is one.)

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, )
