Matlab code for the least square error channel estimation and Minimum Mean Square channele estimation for a MIMO OFDM system. simulation result is compared with theory.

BP神经网络，自适应竞争神经网络对地震进行预测实例(BP neural network, adaptive competitive neural networks to predict the earthquake example)

参考3GPP相关标准并根据LTE技术特征和关键特性，对下行链路级进行设计，包含以下步骤：比特生成、CRC校验、码块分割、编码、速率匹配、码块级联、加扰、调制、层映射、预编码、资源映射、OFDM符号生成和天线映射。为模拟无线传输信道，还需仿真相应的信道模型。收端则是发端的严格逆过程，对接收信号进行一系列处理，得到代表原始发送的信息并判决。(References 3GPP LTE technology standards and in accordance with characteristics and key characteristics of the downlink stage design, comprising the steps of: generating bits, CRC checksum, code block segmentation, encoding, rate matching, code block concatenation, scrambling, modulation , layer mapping, precoding, resource mapping, OFDM symbol generation and antenna mapping. Analog wireless transmission channel, the need to emulate the corresponding channel model. The receiving end is the inverse of the originator of the rigorous, a series of processing the received signal, the representation of the original transmitted information and judgment.)

在fortran中如何调用Matlab，夫有程序(How in the fortran call Matlab, husbands have the program)

说明：  信号x（n）=sin(2*pi*0.05*n)+2*cos(2*pi*0.12*n)+w（n），求N=365的相关函数和功率谱(Signal x (n) = sin (2 * pi * 0.05 * n) + 2 * cos (2 * pi * 0.12 * n) + W (n), the correlation function and power spectrum of n = 365 are obtained)

读取瑞典的雷达数据以及文件头的matlab程序，对于刚刚编写雷达数据处理的入门者来说，是个不错的参考(Read Sweden s radar data and document head matlab procedures, the preparation of radar data for the just treatment of the beginners, it is a good reference)

这是一本关于小波分析的书籍，可以直接使用的，提供给需要的朋友们(this is study on wavelet)

matlab编写的滤波程序，里面包含了滤波前的信号和滤波后的信号。(matlab prepared by the filtering process, which includes pre-filtering the signal and filtered signal.)

The new meshless method based on the cover least square approximation, which utilize cover instead of points that are used in the moving least square approximation, is proposed. For the cover distribution, multi scale voxel data is used for the ease of analysis in 3D solid. Several 3D examples are shown for demonstration. The method is applied to adaptive analysis of seepage flow problem of rock including complicated cracks. The rock model with 3 cracks and 1000 cracks are analyzed

本压缩包里为Chen吸引子的Matlab程序，各参数都是进入混沌状态的标准参数。(compression of the bundle of Chen attractor Matlab procedures, the parameters are entering a state of chaos parameters of the standard.)
