在时间上使用隐式有限差分法，空间上使用后向差分法，对耦合波方程组离散化，进而对受激布里渊散射的能量反射率和产生SBS的阈值能量进行数值模拟。(Begin with the coupled wave equations which describe the interactions of the pump, the sound and the Stokes wave in the process of SBS. The equations are simplified according practical conditions, and one-dimension theoretical models are obtained aiming at unfocused pump as well as focused pump. The coupled equations are turned discrete using the method of implicit finite difference in terms of time and backward difference in terms of space.)

说明：  很好的程序哦！蔡氏系统混沌的matlab代码仿真，有lyapunov指数和分岔图的程序，可以用于混沌系统的研究！(Good program! The matlab code simulation of Chua's chaotic system can be applied to the study of chaotic system.)

这主要是一些课程文档是关于MATLAB神经网络应用设计的，有图像处理相关的，还有编程指导(the book of MATlab which is related with image recognition and MATLAB programing)

运用matlab语言编制的卡尔曼滤波程序。(matlab kalman)

ISI信道下的信号检测和译码的联合迭代算法的实现，编码使用递归卷积码，译码算法为BCJR算法。(Iterative algorithm to achieve joint signal detection and decoding under ISI channel, encoded using recursive convolutional code and decoding algorithm is BCJR algorithm.)

有用的MATLAB小程序，和大家交流一下，下网在这里可以学到很多(useful)

该代码可以用，MATLAB实现图像信息熵计算，在图像处理中很实用，评价图像质量。(This code can be used, MATLAB for image information entropy calculations, image processing is very practical, uate the image quality.)

Okumura analyzed path-loss characteristics based on a large amount of experimental data collected around Tokyo, Japan. He selected propagation path conditions and obtained the average path-loss curves under flat urban areas. Then he applied several correction factors for other propagation conditions, such as: Antenna height and carrier frequency Suburban, quasi-open space, open space, or hilly terrain areas Diffraction loss due to mountains Sea or lake areas Road slope Hata derived empirical formulas for the median path loss (L50) to fit Okumura curves.

说明：  对信道的仿真，采用QPSK调制，分别在瑞利和高斯信道条件下，也包括CRC较验(Simulation of the channel, using QPSK modulation, respectively, Rayleigh and AWGN channel conditions, but also more experience CRC)
