说明：  一个OFDM仿真程序，包含matlab源文件。(An OFDM simulation program, including the matlab source.)

Calculate the Fourier transform of certain pattern like circular aperture, rectangular aperture etc.

This file is the programs of (chapter 9) of book (Modeling the Wireless Propagation Channel a Simulation Approach with MATLAB) which is related The Land Mobile Satellite Channel. It helps you to simulate The Land Mobile Satellite Channe.

双孤子模拟程序，对光纤中的孤子进行仿真，实验结果较理想(Two-soliton simulation program, the soliton fiber simulation, more satisfactory results)

计算工程热力学物性参数，主要用于MATLAB调用Refprop的 (Computational Engineering Thermodynamics physical parameters, mainly used to call Refprop of MATLAB)

说明：  MATLAB以矩阵作为数据操作的基本单位，还提供了十分丰富的数值计算函数。MATLAB和著名的符号计算语言Maple相结合，使得MATLAB具有符号计算功能。(MATLAB with matrix as the basic unit of data manipulation, it also provides a very rich numerical functions. MATLAB and the famous combination of symbolic computation language Maple, MATLAB has a symbolic computing makes.)

emd分解，用于生成本征模态函数，自己看着使用(emd ansys)

认知无线电技术是当前缓解频谱资源紧张的有效解决方案，频谱感知是认知无线电的关键技术，其中，能量检测是经典的频谱感知算法，对于研究频谱感知的初学者来说比较重要。(Cognitive radio technology is an effective solution to alleviate the tension of spectrum resources. Spectrum sensing is the key technology of cognitive radio. Among them, energy detection is a classical spectrum sensing algorithm, which is important for the study of spectrum-aware beginners.)
