QPSK--15

本程序提供了在空间相关信道下，差分空时码的源代码(This procedure provides a channel in the space-related, differential space-time source code)

本文介绍的是一种改进的SPIHT算法，是基于图像编码的小波系数块的，它主要是把四个系数分成一个块，与阈值比较，分出重要与非重要，在进行编码。(This article is a modified SPIHT algorithm is based on the wavelet coefficients of image coding block, it is mainly divided into the four coefficients of a block, compared with the threshold value, separate the important and non important, during the encoding.)

matlab图像去噪经典算法实现 00000000000000000000000(classical image denoising algorithm matlab 00000000000000000000000)

运用matlab对ofdm的原理进行仿真，高效仿真验证ofdm的基本原理(ofdm basic principa)

根据牛顿插值原理进行数据的拟合，附有牛顿插值原理和它的matlab的实现方法，有点简单了，但是过程中的好些地方还是值得学习的。(Newton interpolation carried out in accordance with the principle of data fitting, with Newton interpolation matlab principle and its realization method, a bit simple, but in the process of a number of places it is still worth learning.)

this file is about tutorial for self organizing map

说明：  FCM算法是应用最广泛的聚类分析方法之一，CFCM也是模糊数学中的一种聚类分析算法。 现在给出的这两个算法是C++代码实现的。 (FCM algorithm is the most widely used method of cluster analysis, CFCM is a kind of fuzzy clustering analysis in the algorithm. Now given by the two algorithms is the C++ code to achieve.)

网上复制了一个BP预测的程序自己改了一下，效果不是很好。 P 和T都是往期的数据(Online copy of a program his BP forecast changed a bit, the effect is not very good. P and T are the data to the period)

说明：  人工智能算法在数学建模中的应用，包括遗传算法工具箱，模拟退火算法，蚁群算法等(Application of Artificial Intelligence Algorithms in Mathematical Modeling, including Genetic Algorithms Toolbox, Simulated Annealing Algorithms, Ant Colony Algorithms, etc.)

very excellent matlab textbook , especially for elementary learners
