Communication-System-Simulation-7-8

本书详细介绍了基于近场测试数据的逆散射问题的相关知识及其具体应用，这是近场问题的一个很好的例子，在人们都关注高频远场问题的背景下，提出近场的问题，对于计算电磁学的发展很有启发意义，我们的工程实际中，除了高频远场的应用外，低频近场也占有很大的份额，基于进场的反演是一个新兴的课题，需要我们共同去研究！(Book introduced in detail based on near field test data of the inverse scattering problem related knowledge and its practical application, this is a very good example of near field problems, people are concerned about the background of far field problem of a high frequency in the, near field is proposed, for the development of electromagnetism calculation is instructive. In the actual engineering, in addition to the high-frequency far field of application, low frequency near-field also occupies a large share of, based on the inversion approach is a new and developing subject, we go to study!)

DS-CDMA仿真程序,有大量注释,很值得一看,全面的讲解了CDMA的原理.(DS-CDMA simulation program, has a large number of notes, it is worth a visit, a comprehensive explanation of the principle of CDMA.)

Electronic Communication Systems的Matlab源码，对该书的学习很有帮助(Electronic Communication Systems of the Matlab source code of the book very helpful to study)

模拟陀螺运动程序,本程序是用MATLAB编写的,希望对大家有帮助.(gyro movement simulation procedures, the procedures are prepared by using MATLAB, and I hope to be helpful.)

里边包含了一个如何区分6和9的代码以及用最小距离法、梯度法以及K-NN方法对样本进行的分类代码(Inside contains an example of how to distinguish between 6 and 9, as well as the code with the minimum distance method, the gradient method and K-NN method for sample classification codes)

张正友的标定工具箱，直接运行会有错误，这是经过修改的工具箱，首先运行calib_gui,确认图像目录在current directory里，然后运行calib_gui_normal,出现图形界面，读取图像，进行标定(Zhang Zhengyou calibration kit, run directly there will be a mistake, this is the modified toolbox, first run calib_gui, confirm the image directory in the current directory, then run the calib_gui_normal, graphical interface, read the image, to carry on the calibration)

遗传算法（Genetic Algorithm）是模拟达尔文生物进化论的自然选择和遗传学机理的生物进化过程的计算模型，是一种通过模拟自然进化过程搜索最优解的方法，它最初由美国Michigan大学J.Holland教授于1975年首先提出来的，并出版了颇有影响的专著《Adaptation in Natural and Artificial Systems》，GA这个名称才逐渐为人所知，J.Holland教授所提出的GA通常为简单遗传算法（SGA）。(GA (Genetic Algorithm) is a simulation of Darwinian theory of evolution by natural selection and genetic mechanism of biological evolution of the computing model is a natural evolutionary process by simulating the optimal solution search method, which originally developed by the University of Michigan J.Holland Professor in 1975 first proposed and published an influential monograph " Adaptation in Natural and Artificial Systems" , GA This name was gradually known, J.Holland raised by Professor GA is usually simple genetic algorithm (SGA ).)

汉明码的译码，用Matlab做的，适于初始学习汉明(Han plain code decoding, Matlab do, is suitable for the initial studies the Chinese Ming)

Abstract—Numerous methods have been developed for holistic face recognition with impressive performance. However, few studies have tackled how to recognize an arbitrary patch of a face image. Partial faces frequently appear in unconstrained scenarios, with images captured by surveillance cameras or handheld devices (e.g., mobile phones) in particular.
