MATLAB由于其强大的功能而被广泛应用于很多工程技术领域，尤其在通信和信息处理领域更有其突出地位。众所周知，在物理级的产品作出之前，先用MATLAB进行这种电子产品的输入输出以估计这种产品的性能好坏，从而可以看出什么地方需要从新设计，什么地方需要优化等来进一步提高系统的性能，因此，伴随着现代通信系统与日俱增的复杂性，这种通信系统的仿真分析也变得尤其重要。本文介绍了利用MATLAB进行正交振幅调制与解调的仿真分析，仿真结果验证了该方法的正确性和可行性。(MATLAB because of its powerful features and is widely used in many engineering fields, particularly in the field of communications and information processing more of its prominent position. As we all know, in physics class products made prior to such use MATLAB input and output of electronic products to estimate the performance of this product good or bad, so we can see where the needs of the new design, where the need for optimization to further improve system performance, therefore, accompanied by modern communications systems with ever-increasing complexity, such a communication system simulation analysis has become particularly important. This article describes the use of MATLAB to carry out quadrature amplitude modulation and demodulation of the simulation analysis, simulation results verify the correctness of the method and feasibility.)

基于matlab的通断键控调制模块，跟通信原理书上的2ask调制原理类似，在调用时，需要在主函数中加入调制信号，和进制数，一般是2(Matlab on-off keying modulation of the module, with the Communication Theory book 2ask similar modulation principle, in the call, there is a need to add in the main function of modulation signal, and the hexadecimal number, typically 2)

FDTD方法是把 Maxwell 方程式在时间和空间领域上进行差分化。利用蛙跳式(Leap frog algorithm)--空间领域内的电场和磁场进行交替计算，通过时间领域上更新来模仿电磁场的变化，达到数值计算的目的(FDTD method Maxwell s equations in the field of time and space differencing. Leapfrog (of Leap frog algorithm)- the electric and magnetic fields within the field of space alternating the update time field to mimic the changes in the electromagnetic field to reach the numerical calculation purposes)
