智能天线 自适应非盲算法lms，用MATLAB便携而成(Non-blind algorithm for smart antenna adaptive lms, made portable with MATLAB)

矩形孔菲涅尔衍射图像得计算程序，读者可以修改相关参数，以观察不同形式得菲涅尔衍射图像。(Rectangular aperture Fresnel diffraction image obtained calculation program, readers can modify the relevant parameters to observe the different forms have Fresnel diffraction image.)

Newmark -β法原理Newmark-法是一种逐步积分的方法，避免了任何叠加的应用，能很好的适应非 线性的反应分析。 (Newmark-β law principle Newmark- method is a gradual integration of the ways to avoid any superposition of application, can be well adapted to nonlinear response analysis.)

VMD变分模态分解，vmd函数是通用的，vmd_test是1s专用的，所以只要改test文件，要设一个时间(VMD variable modal decomposition, vmd function is universal, vmd_test is dedicated to 1s, so just change the test file, set a time)

matlab中用来作单位根检测的程序，内有使用说明(matlab in the unit root test used for the procedure, there are instructions)

Abstract The key of developing high frequency wideband communication system is how to model the HF wideband channel. Some HF wideband models are discussed and compared in this paper, including Vogler model, parallel subband model, two improved Watterson models and Pseudo- Deterministic model. As a deterministic model, Volger model basically describes the characteristics of HF wideband channel, but it also needs to be improved. The improvement of Vogler model is given in this paper.
