本设计主要讨论了数字信号2ASK、2FSK、2PSK的调制和解调原理并在matlab中以simulink为平台对这些信号进行了仿真。simulink为用户提供了方框图进行建模的图形接口，采用这种结构画模型图就如同用手在纸上画模型一样自如、方便，故用户只需进行简单的点击和拖动就能完成建模，并可直接进行系统的仿真，快速的得到仿真结果。

论文第一章内容主要介绍了通信的概念，通信系统的组成，以及 simulink的功能；第二章详细介绍 了2ASK、2FSK和2PSK信号调制及解调的原理；第三章是论文的主体主要完成2ASK、2FSK和2PSK信号的仿真，用simulink建模的方法实现调制和解调，各信号都是采用相干解调的方法，而且在解调的过程中在display模块中显示整个系统的误码率。

通过本论文，我更加深入了解了数字通信理论也对Matlab这个功能强大的软件有了一个认识。

楼主提醒：不要机器翻译，本人英语水平还凑合，能看得出是否机译。朋友委托的，苦于专业不对口，对某些专业词汇和句子的理解可能不到位，所以拜托相关专业的英语达人来代劳了。

翻成啥文？
英文？
Mainly discussed the design of digital signal 2ASK, 2FSK, 2PSK principle of modulation and demodulation and simulink in matlab as a platform for the simulation of these signals. simulink block diagram to provide users with a graphical modeling interface, using this model the structure of painting as painting on a piece of paper models by hand, like free, convenient and simple so users can click and drag will be able to complete the modeling and direct simulation, simulation results have been rapid.

The first chapter thesis introduces the concept of communication, communication systems, as well as the function of simulink; chapter details 2ASK, 2FSK and signal modulation and demodulation 2PSK principle; third chapter is mainly to complete the main theses 2ASK , 2FSK and 2PSK signal simulation simulink modeling methods used to achieve modulation and demodulation, the signals are coherent demodulation method used, but also in the process of demodulation
