基于LPP的人脸识别程序，用matlab编程，实现训练，测试，识别等功能(Face recognition based on LPP program，Using MATLAB programming, training, testing, identification and other functions)

matlab下用小波去除随机噪声的一个例子，希望对大家有用(matlab remove the random noise using wavelet under an example, we hope to be useful)

完美的ofdm系统matlab仿真程序，从编解码到加入信道到调制解调到信道均衡到同步和频偏估计，带有详细的程序说明(Matlab simulation ofdm system the perfect program to join from the codec to the modem channel to channel equalization to the synchronization and frequency offset estimation, with a detailed description of the procedures)

说明：  实现多目标粒子群优化功能，重点是进化因子的选取。(Multi objective particle swarm optimization, with emphasis on evolutionary selection factor.)

基于MATLAB实现了极坐标下的傅里叶变换，对一个给定 n×n 的二维信号，其计算复杂度等价于笛卡尔坐标下的2D-FFT，可广泛应用于图像处理和分析。(A fast high accuracy Polar FFT algorithm is given in the software package written in MATLAB. For a given 2D signal of size n×n, the algorihtm s complexity is just like in a Cartesian 2D-FFT, which can be used widely in image processing and analysis.)

使用误差累计的方式，来实时的更新背景，提取出最新的背景，(Cumulative manner using the error to the background of real-time update, extract the latest background)

利用matlab模拟光纤中TE模的模式分布图。(Using matlab simulation model TE mode fiber distribution.)

The simulation file is the Phase lock loop with dq theory with unbalance input volatges

This MATLAB exercise designs and implements a pitch period detector based on detecting and tracking peaks in the autocorrelation of the LPC error signal during regions of voiced speech. The pitch detection procedure is called the SIFT (Simple Inverse Filtering Tracking) method. The SIFT pitch period detector uses a secondary autocorrelation peak in order to detect and correct pitch period detection errors due to effects such as pitch period doubling and related phenomena.
