主要是对图像实现DFT,DCT变换，利用二维小波分析对图像作二层小波分解，显示条状图，十字图及频谱等(Realize the image is mainly DFT, DCT transform, the use of two-dimensional wavelet analysis of images for the second floor of wavelet decomposition, indicating strip maps, charts and cross spectrum)

说明：  这里面包含两个程序段，是学习SIMULINK的基础程序，很有借鉴意义，不学习的就不要浪费时间了(This procedure consists of two paragraphs which is the basis of SIMULINK learning process, referential significance, not to learn not to waste time on)

This code is about HIFU simulator at first we need axisymmetricKZK.m - Driver for axisymmetric KZK integrator

本文档详细介绍了COM中的Marshel机制，深入分析了跨套间通信过程中涉及到的多个问题(This document details the COM in the Marshel mechanism, in-depth analysis of the cross-suite communication process involved in a number of issues)

用于检测微弱信号的Duffing系统，这是我的毕业设计一部分，因为我做的时候也曾求取过很多资料，但是并没有找到，因此在我完成之后，上传这个代码，希望这个能帮助别人。 里面还有后续做的GUI界面实现的Duffing振子检测功能，可检测信号幅值和频率。(The Duffing system for detecting weak signals, this is part of my graduation project, because I also asked for a lot of information when I did it, but it was not found, so after I finished, upload this code, I hope this can help others.)

本书是非常不错的信号检测与估计的书籍！值得一看！(fundamentals of stastic signal processing!)

这是一个基于空时分组编码的MIMO_OFDM通信系统的仿真设计。此系统包括QPSK调制解调，IFFT调制，空时编解码，基于训练符号的信道估计等通信模块。 (This is a space-time block coding based on the MIMO_OFDM communication system simulation design. This system consists of QPSK modulation and demodulation, IFFT modulation, space-time coding and decoding, based on training symbols such as communication channel estimation module.)

var模型的实现。针对var模型的算法，估计模型的参数。并对其进行检验(achieve var model. Var model for the algorithm, the estimated parameters of the model. And its test)
