Intercell Interference Coordination in OFDMA Networks and in the 3GPP Long Term Evolution System

Matlab program to plot the data acquired from the USB (and placed into a CSV file) for the NIA device (Neuro impulse Actuator)

该程序源代码实现了OFDM通信系统性能的仿真，调制方式有BPSK,QPSK,MSK,QAM,信道为AWGN和Rayleigh信道，并对有插入导频的符合IEEE802.11a的OFDM系统进行了仿真。(The program source code to achieve the performance of OFDM communication system simulation, modulation has BPSK, QPSK, MSK, QAM, for the AWGN channel and Rayleigh channel, and have inserted the line with the IEEE802.11a pilot of OFDM system simulation.)

说明：  SVM分类器,关键是对信号进行分类，是模式识别的必备宝典(SVM classifier, the key is to classify the signal is essential for pattern recognition Collection)

Matlab入门教程，内容涉及基础准备及入门； 数值数组及其运算；字符串、元胞和构架数组； 数值计算； 符号计算等等，都有详尽的说明，实属Matlab教程的经典。(Beginning Matlab Tutorial)

EM算法在神经网络中的应用，可以用来进行视频数据分类。(In this demo, I use the EM algorithm with a Rauch-Tung-Striebel smoother and an M step, which I ve recently derived, to train a two-layer perceptron, so as to classify medical data (kindly provided by Steve Roberts and Will Penny from EE, Imperial College). The data and simulations are described in: Nando de Freitas, Mahesan Niranjan and Andrew Gee Nonlinear State Space Estimation with Neural Networks and the EM algorithm After downloading the file, type "tar-xf EMdemo.tar" to uncompress it. This creates the directory EMdemo containing the required m files. Go to this directory, load matlab5 and type "EMtremor". The figures will then show you the simulation results, including ROC curves, likelihood plots, decision boundaries with error bars, etc. WARNING: Do make sure that you monitor the log-likelihood and check that it is increasing. Due to numerical errors, it might show glitches for some data sets.)

说明：  CEEMDAN分解方法，适用于混沌信号，降低其复杂度(Ceemdan decomposition method is suitable for chaotic signals and reduces its complexity)

转,matlab(边界提取,链码生成,差分链码生成及频率向量生成程序)具有旋转不变性了的链码(Turn, matlab (border extraction, chain code generation, differential chain code generation and the frequency of vector generation procedure) has the rotation invariance of the chain code)
