IIRfitler

设计一个四用户的扩频通信系统，扩频增益为N=16，采用Walsh码进行直接序列扩频，BPSK调制，无线信道为AWGN信道。在接收端进行解扩，解调，判决，通过仿真得到其中一个用户的误比特率与信噪比的仿真结果。(Designed a four-user spread spectrum communication system, spreading gain for N = 16, using Walsh code Direct Sequence Spread Spectrum, BPSK modulation, AWGN channel for the wireless channel. At the receiving end for despreading, demodulation, judgments, through the simulation to be one of a user' s bit error rate and SNR of the simulation results.)

改进的粒子群算法在matlab中的应用，程序简单(Improved particle swarm algorithm in matlab, simple procedures)

1采用遗传算法对男女生样本数据中的身高，体重，喜欢数学，喜欢文学，喜欢运动，喜欢模式识别共6个特征进行特征选择，并基于所得到的最佳特征采用SVM设计男女生分类器，并计算模型预测性能（包含SE,SP,ACC和AUC ）。提示：可以用6位的0/1进行编码，适应度函数可以考虑类似 。(1 genetic algorithm for boys and girls in the sample data of height, weight, like math, like literature, like sports, like pattern recognition feature a total of six feature selection, design and use of SVM classifier for boys and girls based on the best features of the resulting and calculating prediction performance model (including SE, SP, ACC and AUC). Tip: 6 may be encoded with the 0/1, the fitness function may be considered similar.)

这是一个标准的基本粒子群算法，可以在此基础上加入fun函数完成解。(This is a standard basic particle swarm algorithm, which can be added fun function to complete the solution.)

说明：  ransac算法Matlab 实现 RANSAC算法全称是随机抽样一致算法（random sample consensus,RANSAC），RANSAC算法的基本假设是样本中包含正确数据(inliers，可以被模型描述的数据)，也包含异常数据(outliers，偏离正常范围很远、无法适应数学模型的数据)，即数据集中含有噪声。(The ransac algorithm Matlab achieves the RANSAC algorithm's full name is the random sample consensus (RANSAC). The basic assumption of the RANSAC algorithm is that the sample contains the correct data (inliers, data that can be described by the model) as well as outliers (outliers). The normal range is too far to fit into the data of the mathematical model. That is, the dataset contains noise.)

空时编码源代码，在Matlab中使用Mex文件编写，速度快(space time codec)

经典的matlab算法代码，包括顶点覆盖近似算法，哈密尔顿回路，最短路和次短路，最短路径等等。(Classical algorithm matlab code, including the vertex cover approximation algorithm, Hamilton circuit, the most short-circuit and sub-circuit, the shortest path and so on.)

本程序是用matlab实现的对样本视频处理,本视频是用于识别羽毛球拍的运动轨迹，经检测，实现完好。(This procedure is implemented by matlab sample video processing, the video is used to identify the racket trajectory, after testing, to achieve well.)
