matlab空间梁单元有限元源程序beam3d。(Matlab space beam FEM source beam3d.)

Here is a code for image restoration after compression. Using this you can calculate system parameters like PSNR, BER, CR

这些都是通信系统仿真与分析一书的源代码，希望对初学者有用，从基本的理论很好的用matlab进行了最基本的仿真(These are the communications system simulation and analysis of the source code of the book, I hope useful for beginners, from the basic theory of good use to the most basic matlab simulation)

说明：  采用身高和体重数据作为特征，分别假设二者相关或不相关，在正态分布假设下估计概率密度，建立最小错误率Bayes分类器，写出得到的决策规则，将该分类器应用到训练/测试样本(Bayes classifier is the most classic! Minimize the classification error. With the matlab language, with examples)

说明：  MATLAB程序，Writing Fast MATLAB Code(MATLAB program, Writing Fast MATLAB Code)

模拟车载移动信道产生的瑞利衰落，默认为6径衰落，移动速度可以设定，车载移动信道的仿真常用模型 (Simulate vehicle movement generated by Rayleigh fading channel, the default is 6-path fading, mobile speed can be set, in-car mobile channel simulation model used)

电动公交车的充电负荷计算，蒙特卡洛法，电动汽车充电负荷模型(Electric bus charging load calculation, Monte Carlo method, electric vehicle charging load model)

一个四用户的扩频通信系统，扩频增益为N=16，采用Walsh码进行直接序列扩频，BPSK调制，无线信道为AWGN信道。在接收端进行解扩，解调，判决，通过仿真得到其中一个用户的误比特率与信噪比的仿真结果。(A four-user spread spectrum communication system, spreading gain for N = 16, using Walsh code Direct Sequence Spread Spectrum, BPSK modulation, AWGN channel for the wireless channel. At the receiving end for despreading, demodulation, judgments, through the simulation to be one of a user' s bit error rate and SNR of the simulation results.)

matlab环境下求可靠性的程序，主要部分为求取最小路，采用容斥公式求可靠度

使用MATLAB对数字基带信号进行仿真的缘带码.仿真后结果有高斯噪声(use MATLAB for digital baseband signal simulation code geopolitical zone. Simulation results after a Gaussian noise)
