这是基于增广矩阵束的L型阵列的二维DOA估计MATLAB程序。(this is a matlab program about DOA.)

本程序是本人根据人脸识别PCA改进的，用于掌纹识别，是学习PCA特征提取的很好的学习资料。(I based this program is to improve the face recognition PCA for palmprint identification, PCA feature extraction is to learn a good learning materials.)

运用粒子群优化算法对ARMA(p,q)模型的阶数进行优化是可行的，且利用优化后的ARMA模型对航空发电机状态趋势进行分析的结果十分准确，与原始数据所表现出的航空发电机状态变化趋势基本一致。经计算，此时分析结果的平均相对误差较小，仅为1.38 ，与优化前构建的ARMA模型相比，平均相对误差降低0.23个百分点，优化效果明显。(Using particle swarm optimization algorithm to optimize the order of the ARMA (p, q) model is feasible, and the use of the results of the ARMA model optimized air generator status trends analysis is very accurate, and the raw data showed aviation the generator status consistent trend. Calculated analysis of the results, the average relative error is small, only 1.38 , compared with the the ARMA model built before optimization, average relative error is reduced by 0.23 percentage points, to optimize the effect is obvious.)

利用区域协方差，找出两幅图相似的地方，准确度很高(Use of regional covariance identify the similarities of the two images, high accuracy)

这是计算机插直的matlab算法集锦,全面而有用,对从事数值计算方面的朋友很有帮助!(This is a computer algorithm matlab interpolation straight allehanda, comprehensive and useful aspects of numerical computation involved in helpful friend!)

基于 MATLAB 的时域信号采样及频谱分析，是很好的学习时域信号的matlab源代码。(MATLAB-based time-domain signal sampling and spectral analysis, is a very good study of time-domain signal matlab source code.)

tA scheme of format conversion optical 16-ary quadrature amplitude modulation (16QAM) toquadrature phase shift keying (QPSK) signal based on cascaded four-wave mixing (FWM) in semiconduc-tor optical amplifiers (SOAs) is proposed. Theoretical analysis and simulations of the format conversionscheme are conducted to validate the feasibility of the proposal. In this proposal, the phase conjugatedof 16QAM signal is generated after the first FWM process in an SOA, and then the QPSK signal is con-verted due to the second non-degenerate FWM (ND-FWM) process in another SOA. The performance andthe optimal design of the 10 Gbit/s format conversion system under various key parameters of SOAs are uated and discussed. Simulation results present useful to enable interconnection between backbonenetwork and access network.
