matlab图像处理命令详细说明（中文版） 省去了看英文帮助文件的烦恼(Matlab image processing orders detailed description (Chinese version) save a document of English to help the trouble)

本人编写的一个根据五行八卦理论用来测试手机号吉凶的小程序,本程序只供大家消遣,且莫过于在意,呵呵()

说明：  实现了神经网络PID算法的编程,通过神经网络在线调节PID参数(MATALB BP PID sfunction)

说明：  本程序仿真了电子扫描阵列天线方向图，实现了不同参数情况下栅瓣现象、主瓣宽度和功率增益随扫描角变化情况(This program simulates the electronic scanning array antenna pattern, and realizes the change of grating lobe phenomenon, main lobe width and power gain with scanning angle under different parameters.)

本论文以OFDM系统为基础，介绍了OFDM系统的基本原理，以及使用OFDM技术的优势所在，并且展望了今后的无线移动技术的发展前景。在简单介绍OFDM原理的同时，着重阐述了OFDM系统在不同信道环境和不不同实现方式下的误码性能。主要包括了OFDM系统在加性白高斯信道，在加性白高斯信道和多径干扰两种不同信道环境下系统的误码性能，其中后者还研究了系统在有保护间隔与无保护间隔的误码性能比较。在理论分析的基础 (This thesis is based on the OFDM system, the basic principle of the OFDM system, as well as the advantages of using OFDM technology, and future prospects for the development of future wireless and mobile technologies. OFDM principle in brief, focusing on the BER performance of OFDM systems under different channel conditions and different implementations. Including OFDM system in additive white Gaussian channel, additive white Gaussian channel and multipath interference of two different channel environment, the system BER performance, the latter of which also studied the system in a protected interval without guard interval BER performance comparison. The basis of theoretical analysis)

说明：  基于空间调制的matlab代码，可完整运行(Matlab code of wireless communication system based on spatial modulation)

认知无线电模型建立,频谱感知环境，可以选择认知用户授权用户个数(create the cognitive radio model)

说明：  无源被动雷达对目标进行定位之生成雷达信号,产生信号(Passive Radar Detection using Range-Doppler Transformations generate signal)

基于matlab的水下通信系统仿真及波束形成算法(Underwater communication system)

说明：  中兴h608b备份文件，usb口恢复超级管理员帐号(ZTE h608b backup file, usb super-administrator account to restore the mouth)
