恒模算法的matlab实现，这是个人的一点看法，对于不同的电脑可能会有不同的小问题，仔细检查即可(Constant modulus algorithm matlab realize, this is a personal point of view, may be different for different computers, double-check to)

说明：  matlab 实现 付费通变换 抽取的另一种算法(matlab FFT transform taken to achieve an alternative algorithm for)

MATLAB实现大气湍流随机相位屏，以傅里叶变换为基础，增加了低频次谐波补偿 使相位屏仿真更加准确(atmosphere random phase is realized with MATLAB.)

使用MATLAB语言实现BP神经网络的分类功能，代码很简洁(using MATLAB BP neural network classification function, a very simple code)

认知无线电环境中，当认知用户处于低信噪比环境时，软判决与硬判决的对比发现此时软判决优于硬判决(In Cognitive radio environment, the cognitive users in low SNR environment, the contrast of the soft decision and hard decision to soft decision is better than hard decision)

DCT变换：变换域系数选取采用阈值编码，：阈值越小，图像恢复效果越好，但压缩效果差，一般取在5-10 即可很好的获得恢复图像信息。(DCT transform: transform domain coefficients selected using the threshold coding: the smaller the threshold value, the better the image restoration, but the compression is poor, and generally in the 5-10 to get a good recovery image information.)

卷积神经网络是人工神经网络的一种，已成为当前语音分析和图像识别领域的研究热点。它的权值共享网络结构使之更类似于生物神经网络，降低了网络模型的复杂度，减少了权值的数量。自己可已加入数据，和修改梯度。(Convolutional neural network is an artificial neural network, it has become a research hotspot speech analysis and image recognition field. It weights shared network structure to make it more similar to biological neural networks, reduce the complexity of the network model, reducing the number of weights. Own data may have been added, and modify gradients.)

it is code of finding QRS of a ECG waveforms.

matlab dsp(1． 利用自相关函数法和周期图法实现随机信号的功率谱估计。 2． 观察数据长度、自相关序列长度、信噪比、窗函数、平均次数等对谱估计的分辨率、稳定性、主瓣宽度和旁瓣效应的影响

基于前人读取LIDAR数据并且显示给与解释和增加写内容 (LIDAR data based on previous reads and displays content to give explanations and to increase writing)
