一个小的lindo，做数学建模的同志们应该知道吧，不知道你们用得上不。以后有好东西再给大家送来(A small lindo, make mathematical modeling comrades should know, I do not know you is not useful. After the U.S. has brought good things to give)

FBMC滤波器组多载波系统的方针程序，采用OQAM调制。可以和OFDM系统做个对比(FBMC （filter bank multi-carrier) OQAM)

hmm 说话人识别 matlab 算法，c++算法，(speaker recognition hmm)

蓄电池双向Boost/Buck充放电控制，与电网结合。(Battery bi-directional Boost/Buck charge and discharge control, combined with the grid.)

说明：  各种matlab 算法使用指南，及其相关命令的使用方法介绍.(guide for otimization method used in matlab)

说明：  很重要的指纹识别算法是基于matlab下的配合调用matlab的gui界面,使用这种算法可以提高matlab的运算效率。(the code base on the matlab and it will do well in gui in matlab if you use it you will find good way to identify the picture of finger)

关于OFDM的论文，希望对大家有帮助。Performance Analysis of Pulse Shaping Technique for OFDM PAPR Reduction(Performance Analysis of Pulse Shaping Technique for OFDM PAPR Reduction)

彩色图转灰度图++matlab+实现代码，很不错，值得看看！(Color to grayscale++matlab+ implementation code, very good, worth a look!)

一、穆勒矩阵构成 穆勒矩阵是一个4*4的矩阵，完整描述了介质的偏振属性。可通过水平线偏振光H、垂直线偏振光V，45°线偏振光P，右旋圆偏振光R入射，并分别探测水平线偏振光H、垂直线偏振光V，45°线偏振光P，右旋圆偏振光R出射情况下的能量值，即16种偏振态组合下的强度结果，HH/ HV/ HP/ HR，PH/ PV/ PP/ PR，VH/ VV/ VP / VR和RH/ RV/ RP/ RR。进而Mueller矩阵可按照公式（1）计算得到：(First, the Muller matrix The Muller matrix is a 4*4 matrix that completely describes the polarization properties of the medium. The horizontal line, vertical line polarized light polarized light H V, 45 degrees P linearly polarized light, right circularly polarized incident detection and R, respectively, H vertical horizontal line polarized light polarized light V, 45 degrees P linearly polarized light, right circularly polarized light R emitted under the condition of energy intensity results of 16 kinds of polarization combinations HH/ HV/, HP/ HR, PH/ PV/ PP/ PR VH/, VV/ VP and RH/ RV/ RP/ RR / VR. Furthermore, the Mueller matrix can be calculated according to formula (1):)

降低OFDM系统误码率，剖析了OFDM系统在非线性失真影响下的PAPR过高的原因和影响，以及消除多普勒频移和多普勒扩展对 OFDM 系统的影响，并针对两个方面进行相应的性能改善工作，降低PAPR以及多普勒频移的影响，减少了以往方法带来的不良影响，进而改善了OFDM通信系统的性能。
