this r program for QUADRATURE AMPLITUDE MODULATION AND QPSK

digital signal processing

说明：  利用MATLAB编写的该算法可以对小球碰撞的过程进行模拟(Prepared using the MATLAB algorithm for small ball to simulate the process of collision)

单相H桥多电平逆变器控制电路，基于matlab2014b环境下编写(Single-phase H-bridge multi-level inverter control circuit, based on the following written matlab2014b environment)

模式识别中的模糊聚类，采用隐马尔科夫链，考虑了先验概率，进行图像识别。(Pattern recognition, fuzzy clustering, using hidden Markov chain, taking into account a priori probability for image recognition.)

说明：  matpowe7.0,Open source software, no modified version downloaded from the official website,the new MOST can calculate timing OPF,but the DC model may not be accurate

wavelet小波处理算法及其应用。包含了小波处理的基本应用，图像的去噪等等处理(wavelet implementation)

升降压DC——DC变换器的simulink模型，前相为buck变换器，后相为boost变换器，可以进行适当的升降电压调节。(The buck-boost DC- DC converter simulink model, phase buck converter, the latter phase of the boost converter can be appropriate lifting voltage regulator.)

说明：  将线性模型拟合为线性或二次数据。 它是一个演示线性回归的脚本。 有益于学习(Fit a linear model to linear or quadratic data)

利用霍夫变换原理求解圆环的圆心，以及半径(The Hough transform principle solving Rings center of the circle, as well as the radius)
