运用MATLAB求解的圆环的滚动运动，希望对大家有帮助。(circle)

卷积码的编码、维特比译码，已调试成功，可直接使用(Convolutional code encoding, Viterbi decoding, has been debugged, can be used directly)

说明：  求mel频率倒谱系数的程序，求的准确，时间相比其他程序多一点(Mel frequency cepstrum seeking the procedure, find the exact time a little more compared to other programs)

SVM非线性分类，数据与代码均给出，而且还有结果图列，望能给予帮助(SVM linear classification, data and code are given, but also the results of figure out, hope for help)

本程序给出了采用Turbo编码及其信道估计的OFDM的性能仿真。采用时域LS信道估计。对于初学OFDM及信道估计的非常有帮助。(This program is used to simulate the performance of OFDM with turbo coding and time domain LS channel estimation. It is useful for the primer for learning OFDM systems and channel estimation algorithms.)

给出了线阵的指向性计算matlab代码，并绘制指向性指数(Gives the linear array of point calculations matlab code, and draw the point index)

使用matlab函数，，，实现用熵值法求出任意矩阵的行或列的权重和每个值的综合参数(Entropy Method )

压缩感知的贪婪迭代算法，算法使用最小二乘估计来重构信号(Greedy iterative algorithm compressed sensing algorithms to reconstruct the signal using a least squares estimation)

说明：   该电路由一片四双向模拟开关集成电路CD4066为核心构成。每个电路内部有四个独立的能控制数字或模拟信号传送的开关。当水箱无水时，由于180K电阻的作用，使四个开关的控制端为低电平，开关断开，LED 不发光。随着水位的增加, 由于水的导电特性，使得IC的13脚为高电平，S1接通，LED1点亮。当水位逐渐增加时，LED依次发光指示水位。水满时， LED4发光， 显示水满。同时T1导通， B发出报警声，提示水已满。不需要报警声时，断开开关K即可。 (The circuit consists of a four-way analog switch integrated circuit CD4066 core composition. Within each circuit to control four separate digital or analog signal transmission in the switch. When the tank water, the role of the 180K resistor, so that the four low-side switch control, switch off, LED does not light. As the water level increases, the electrical properties of water, making the IC' s 13 feet high, S1 connected to, LED1 lights up. When the water level gradually increased, LED turn light level indication. Is full of water, LED4 LED display full of water. At the same time conducting T1, B alarm will sound, indicating that the water is full. Do not need to sound the alarm when the disconnect switch K can be.)

本程序实现了对无线电覆盖的3D仿真，包括反射效应的2D模拟以及基于接收端与发射端距离的功率衰减。并实现基于Matlab的3D仿真。(The program 3D simulation of radio coverage, including 2D simulation based on the receiving end and the transmitter end distance power attenuation of the reflection effect. And to achieve the 3D simulation based on Matlab.)
