beamforming by LMS algorithm in CDMA communication

说明：  信号实验常用的simulink模型和mfile,可直接在matlan下运行。(Simulink signals commonly used in experimental models and mfile, can be run directly in matlan.)

此m文件为脚本文件，在命令窗口输入命令：midamble，即可执行！ 单元数组--user_m，存储了K个用户的midamble码，user_m{1}对应用户1，以此类推。(This m file for the script file, enter the command in the command window: midamble, which can be executed! Cell array- user_m, stored K users of the midamble code, user_m (1) corresponds to user 1, and so on.)

该方法 基于快速傅里叶变换，求解方形区域的poission方程 比差分 有限元快。

matlab的发展环境,为解决大型迭代法的非线性方程组,M-file(matlab development environment, broyden iteration method for solution of nonlinear equations, in which M-file)

说明：  1.1 背包问题 有一个徒步旅行者，已知他能承受的旅行背包的重量不超过a（kg）。设有n种物品可供他选择装入背包，这n种物品分别编号为1，2，…，n。其中第i种物品每件的重量为ai（kg），其使用价值（指一件第i种物品对旅行者来说所带来的好处的一种数量指标）为ci（i＝1，2，…，n）。问这位旅行者应如何选择携带这n种物品的件数，使得总价值最大？ (1.1 knapsack problem is a hikers. he is known to travel to withstand the weight of the backpack not exceed a (kg). N Species with articles for his choice loaded backpack, n product were numbered 1, 2, ..., n. I first of which product each ai of the weight (kg), its value (i refers to a section of the types of items travelers the benefits brought by a number of indicators) for the ci (i = 1, 2, ..., n). Asked how travelers who choose to bring this product to the n pieces, making the total value of the largest?)

在自适应波束形成算法中，使用阻塞矩阵法抑制主瓣干扰(In adaptive beamforming algorithm, using blocking matrix interference suppression in the main lobe)

说明：  个人编写的基于matlab的sobel算子算法(Personal preparation of the matlab-based algorithm sobel)

3. Setting of a suitable threshold value.Then apply wavelet de-noising and compression on wavelet coefficients and thresohlding using global positive threshold value. So that a compressed image can be transmitted in an efficient manner.

“基于Matlab的MIMO通信系统仿真”，，收获良多，特将其记录下来("Simulation of MIMO Communication System Based on MATLAB", which has gained a lot, is specially recorded.)
