频谱感知中基于自适应阈值的能量检测算法研究 频谱感知能力是认知无线电通信的一个重要前提和关键技术，而能量检测技术作为传统的信号检测方法的基础，具有容易实现，低计算复杂度，不需先验知识等优点，具有重要的研究价值和应用前景。(Energy Detection Algorithm)

说明：  利用最小熵法球时间延迟，可以用在TDOA定位中(The ball by the time delay of minimum entropy method can be used in TDOA positioning)

This is a Huffman code, display the average bits.Works with .txt

基于matlab的空间圆弧插补与仿真，每个函数独立编写成为m文件，规范化编程接口，希望对大家有用处 (Space-based matlab circular interpolation and simulation, each function independently write m file become standardized programming interfaces, we hope to be useful)

利用FFT方法和维纳-辛钦定理自相关函数获得功率谱的对比。(Using FFT method and Wiener- Khintchine theorem to obtain the autocorrelation function of the power spectrum contrast.)

Face recogination using PCA in matlab

本程序的功能是用支路追加法求阻抗矩阵,再用三相短路计算短路电流和电压(The function of this procedure is to use branch supplementary method for impedance matrix, with a three phase short circuit calculation of short circuit current and voltage)

自己编的闻邦椿书上的Riccati求转子临界转速，转子为单跨双转盘。有去除奇点，提取振型，收敛迭代为弦截法。有各向异性求取临界转速部分，不过结果可能不准确。(Riccati Wen Bangchun own series of books on demand critical speed rotor, the rotor is a single span double turntable. There are singular point removal, extraction modes, the convergence of iterations for the Secant method. Anisotropy strike critical speed section, but the results may be inaccurate.)

说明：  提出一种预测电流型三相逆变器的SVPWM控制策略,利用Matlab/Simulink搭建了预测电流型三相逆变器的SVPWM控制的仿真模型(This paper proposes a SVPWM control strategy for predictive current three-phase inverter, and uses Matlab / Simulink to build a simulation model of predictive current three-phase inverter.)
