现在通信系统中直扩信号的衰落信道建模的matlab程序(Now Communication System DS signal fading channel modeling matlab program)

说明：  用于计算高频下的金属介电常数，主用侧重应用于有限元分析仿真中金属材料的物理属性。(The metal used to calculate the high frequency dielectric constant, the main emphasis used with finite element analysis simulation of the physical properties of metal materials.)

Motion estimation algorithm - three step search

潮流准调和分析 Dd.m [DO1 dO1 DK1 dK1 DM2 dM2 DS2 dS2 DM4 dM4 DMS4 dMS4]=Dd(y,D,Y,tm,A1) 计算6个准调和分潮的振幅系数和初相角公式 aM.m [N n aa liu_u liu_v]=aM() 基础系数矩阵，目前D和d值是取用的各段数据的中间时间值，t是以中间为0左右对称取； 视差潮龄A1需要预先得知 同时本程序负责读取原始测流数据，格式为 站位名称 观测数据段数N（即大 中 小潮） 第一段起始时间YYYY MM DD HH mm ss 第一段个数n1 speed direction speed direction ... 第二段起始时间 YYYY MM DD HH mm ss 第二段个数n2 speed direction speed direction ... 第三段起始时间 YYYY MM DD HH mm ss 第三段个数n3 speed direction speed direction ... UVg.m [U V Ug Vg]=UVg() 求调和常数U V和迟角Ug Vg Tuoyuan.m 计算各准调和分潮的椭圆要素W theta K k (The quasi harmonic analysis of tidal current Dd.m [DO1 dO1 DK1 dK1 DM2 dM2 DS2 dS2 DM4 dM4 DMS4 dMS4]=Dd (y, D, Y, TM, A1) calculation of 6 quasi harmonic division of amplitude and initial phase angle formula of the coefficient of tide AM.m [N n AA liu_u liu_v]=aM () foundation coefficient matrix, the current D and D values are the middle time of each section of data taken the value of T is in the middle for symmetric about 0 Age of parallax A1 need to know in advance At the same time, this program is responsible for reading the original flow measurement data, format for Site name The observation data segment number N (that is, in the low tide) The first section of the YYYY MM DD HH mm the starting time of SS The first section number N1 Speed direction Speed direction ...

计算双层单负材料的色散关系投影能带图 (the dispersive relation of the twwo single negative metamaterial layer )

第3个：matlab 和C++联合用于SLSVM，另外一种风格的(the 3file: matlab and c++ together for SVM)

说明：  一个协方差交集的matlab函数,可以直接调用的函数(Matlab code on intersection of a covariance.The function can be directly called)

说明：  信息科学与通信工程中信息论编码的RS码函数的编写(Information Science and Communication Engineering, Information Theory encoded RS codes in the preparation of the function)

说明：  matlab的命令大全，希望对大家有帮助呵呵，主要是一些命令咯 (Matlab orders, hope to help you, is mainly some orders)

说明：  该程序师用MATLAB实现的，作用是绘制图像的二维直方图(The programmers used MATLAB to achieve, is to draw two-dimensional histogram of the image)
