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.)

自适应控制，自校正控制系统参数估计matlab程序，利用递推最小二乘法进行系统参数估计(Adaptive control, self-tuning control system parameters estimated matlab procedures, the use of recursive least squares method for system parameter estimation)

采用极大值法实现图像处理中的小波去模糊。基于matlab函数实现。(Using the maximum value method to achieve image processing wavelet deblurring. Based on matlab function implementation.)

从excel中提取数据，应用小波包分解提取特征频段能量值的matlab程序(Extracting data from excel, the wavelet packet is used to decompose the matlab program that can measure the value of the feature frequency)

说明：  当用户已知系统的输入和输出时，该程序可用来估计系统的参数！(Known system inputs and outputs, it is estimated the parameters of the system!)

本程序用于对加工夹具进行受力分析 预测被动力(The procedure for processing fixture for prediction by dynamic mechanical analysis)

CRS 去噪代码，可以在matlab上运行，是从别的地方找来的。测试或可以用(CRS denoising code can be run in matlab, is recruited from elsewhere. Test or you can use)

power_transfo.rar,功率电子领域matlab仿真文件，已经验证过，程序运行正常(power_transfo.rar,Power electronics field matlab simulation file, has already been verified, the normal operating procedures)

hdb3 AMI 码 这是自个儿用matlab编的关于HDB3，AMI的仿真 (hdb3 AMI)
