helpful hints for adaptive MIMO in mat lab
这是用MATLAB实现的有限数字滤波器设计,与发的滤波器设计一起学,效果会更好(This is achieved using MATLAB limited digital filter design, the filter design and development with science, the effect will be even better)
线性调频信号是一种雷达常用的电磁波信号,当雷达信号检测到目标时候,反射后得到雷达回波信号(LFM signal is a kind of radar used electromagnetic signals, when the radar signal detection to the target, the reflection of radar echo signal after)
y3k=fft(u,(m+n-2)/4) i=1:(m+n-2)/4 subplot(5,2,9) stem(i,u) title( 滤波后上采样 ) k=1:(m+n-2)/4 subplot(5,2,10) stem(k,y3k) title( 上采样频谱 ) xlabel( k ) ylabel( y3k ) (y3k = fft (u, (m+ n-2)/4) i = 1: (m+ n-2)/4 subplot (5,2,9) stem (i, u) title (after filtering the sample) k = 1: (m+ n-2)/4 subplot (5,2,10) stem (k, y3k) title (on the sample spectrum) xlabel (k) ylabel (y3k))
说明: matlab 用 于 统 计 分 析 的 程 序 和 应用(matlab program for statistical analysis and application)
说明: gaosi 信道的m文件,通信中必须要的仿真文件(m channel gaosi documents, communication must be of the simulation file)
大气模型计算,本软件可实现计算不同高度的密度、气压等参数。(Atmospheric model calculations, the software can realize a high degree of different density, pressure and other parameters.)
描述了运用MATLAB命令将M文件翻译为C语言程序,并修改为可直接调用的C语言函数的方法,使用该方法所需要注意的方法局限性和MATLAB版本差异的影响。运用该方法将能够使C语言能直接使用MATLAB当中已经完成的数学计算功能,大大扩充了C语言的数学计算功能和开发效率(err)
TFIND searches for one or more strings (boolean AND) in a text file. TFIND reports all lines where the string(s) were found (or NOT found by option). The search can be limited to a field in a fixed field (i.e. column oriented) list. An extended search mode is available, where only letters and digits are relevant. Other options: case sensitive search, alternative errorlevel with number of hits, header line with file name, LFN, custom prefix
在简要介绍MATLAB语言的基础上,对使用MATLAB语言仿真的CDMA通信系统进行描述。(in MATLAB briefed on the basis of on the use of MATLAB simulation of CDMA communications system description.)
