说明：  模糊正系统的判定及稳定性分析，相比一般的稳定性分析我的有独特之处(Fuzzy is the system and stability analysis to determine )

OFDM(Orthogonal Frequency Division Multiplexing)即正交频分复用技术，实际上OFDM是MCM Multi-CarrierModulation，多载波调制的一种。其主要思想是：将信道分成若干正交子信道，将高速数据信号转换成并行的低速子数据流，调制到在每个子信道上进行传输。正交信号可以通过在接收端采用相关技术来分开，这样可以减少子信道之间的相互干扰 ICI 。每个子信道上的信号带宽小于信道的相关带宽，因此每个子信道上的可以看成平坦性衰落，从而可以消除符号间干扰。而且由于每个子信道的带宽仅仅是原信道带宽的一小部分，信道均衡变得相对容易。本程序实现OFDM与QPSK技术的比较(This program realization technology and the OFDM QPSK technology)

说明：  MIMO OFDM MMSE calculation

The aim of the assignment is to understand the concept of the image enhancement stage We need to know the technique to improve the image or better input for the image processing technique as in the assignment. In the first part of the assignment is the segmentation using thresholding technique. Before we threshold the image, we need to prepare the better image for input such as histogram equalization to stretch the intensity value of the image before converting to binary image. In the second part of the assignment is about frequency domain. We need to transform the spatial image to frequency image using Fourier transform of the image before using the filter.

说明：  IEEE14节点潮流计算程序。程序最初的数据模块可以修改成别的，如IEEE30节点和57节点的等等，矩阵取名用的是中文拼音(IEEE14 node flow calculation program)

使用BP算法实现压缩感知信号重构,需要已知观测空间基矩阵和观测向量(BP_Simplex,BP with a Simplex mplementation)
