关于IQ解调的一些matlab例程

此文档是介绍孤子在饱和介质中传输的matlab仿真过程，孤子仿真网上有很多文章，可是均不带源码，恰巧本人编了些就都传上了，希望对各位有用。(Introduction This document is at saturation soliton transmission medium matlab simulation process, there is a lot of soliton simulation online article, but not with source code, I made something happen on both a mass on the hope that useful to you.)

这是在机器学习、人工智能、数据挖掘中经常用到的数据集，聚类分析也经常用，包括：UCI的数据集wine,yeast,iris等，还有USPS数据集，4k2_far,leuk72_3k数据集等。(This is in machine learning, artificial intelligence, data mining frequently used data sets, cluster analysis are often used, including: UCI datasets wine, yeast, iris, as well as USPS datasets, 4k2_far, leuk72_3k datasets and so on.)

说明：  使用MATLAB对MIMO系统进行辨识，其中有各种算法仿真算例，N4SID，针对多变量系统的一种识别算法(MOESP (Multivariable Output-Error State sPace) is a deterministic method to identify linear time invariant systems. The MOESP method developed by M. Verhaegen and P. Dewilde is based on the LQ decomposition of Hankel matrix formed from input-output data, where L is lower triangular and Q is orthogonal. A Singular Value Decomposition (SVD) can be performed on a block from the L (L22) matrix to obtain the system order and the extended observability matrix. From this matrix it is possible to estimate the matrices C and A of state-space model. The final step is to solve overdetermined linear equations using the least-squares method to calculate matrices B and D.)
