brain tumor detection using matlab

用matlab绘制线性调频信号的时域波形，同时对信号进行频谱分析，并考察采样频率以及信噪比对频谱分析的影响。(Matlab drawing with linear frequency modulation signal time-domain waveform, and spectral analysis of signals and the sampling frequency and signal to noise ratio study of the impact of spectrum analysis.)

非静止多波束声呐混响的自回归模型。综合考虑了环境，几何结构等多种因素通过时变自相关函数仿真混响复数据序列。(This work describes a technique for simulating nonsta- tiouary multibeam Gaussian sonar reverberation sequences. The primary objective is to simulate quadrature-demodulated complex digital vector sequences that have a prescribed time-variaut Covariance function. )

小波实现图像压缩的程序，matlab仿真，可以下载下来学习一下，简单易懂(Wavelet image compression of small procedures, to share)

此为许多关于图像处理的程序,对处理图像大有帮助,希望与大家分享.(This is a lot about image processing procedures for dealing with images of great help and hope to share with you)

本程序实现不用对数据进行2抽取和2插值的快速小波分解,只需对滤波器进行2插值即 可，所以不要求数据的长度为2的幂次方，共分解了3次，然后进行了重构！！！(This procedure achieved without the data extraction and 2 Fast 2 interpolation wavelet decomposition, only 2 of the interpolation filter that can be, so the data length does not require a power of 2, a total break down three times, then refactored! ! !)

说明：  主要讨论了QPSK的调制解调原理，分析了它们的调制解调实现过程(Mainly discussed the QPSK modulation and demodulation principle, an analysis of their realization of the process of modulation and demodulation)

牛顿插值法的MATLAB实现，信号分析处理 综合实验6的必须选择部分， 信号分析处理高级要求。(Newton interimpose method, for signal process and analysis advanced lab of such a class.)

kde全称是kernel density estimation.基于核函数的概率密度估计方法。是模式识别中常用的算法之一(KDE which is kernel density estimation is used to estimate probabilty function. It is mostly used in pattern recogntion)

说明：  这是一个通用的宽带模拟器上基于OFDM分组传输系统为基础。它要求MATLAB版本6.0或更高。(This is a generic simulator-based broadband packet transmission system based on OFDM. It requires MATLAB version 6.0 or higher.)
