Channel_Estimation

车牌识别，识别准确率不高，但是可用，适合初学者探索matlab之用。(License plate recognition, recognition accuracy is not high, but is available for beginners to explore the use of matlab.)

说明：  按照对应的数字语音信号的短时帧，求出它的过零率。(Digital voice signals in accordance with the corresponding short-time frame, find its zero rate.)

qpsk constellation simulation under rayleigh fading channel(qpsk constellation simulation under rayl eigh fading channel)

本函数用于估计固定效应面板空间误差（Panel SEM)模型( computes spatial lag model estimates for spatial panels )

增量式PID控制算法：相比位置式PID控制有更好的控制精度，不累加误差，误动作影响小，不易引起积分饱和(Incremental PID control algorithm: compared to the position PID control has better control accuracy, and does not accumulate error, malfunction affect small, are unlikely to cause the windup)

利用VFSA法对地震剖面进行反演测试，可以用来测试模拟退火法是否可以用于实际模型。(Use VFSA method seismic inversion tests can be used to test whether the simulated annealing method can be used in the actual models.)

直流电动机的所有相关例程的MATLAB/simulink仿真实例，对大家学习直流电动机有很大的帮助。(Dc motor all related routines of MATLAB/simulink simulation examples, is of great help for everybody to learn dc motor. )

说明：  在matlab实现的zigbee源代码，并有相关论文做描述，比较全面(Zigbee achieved in the matlab source code, and have the relevant papers to do a description of a more comprehensive)

脉冲多普勒雷达接收信号，进行快速傅里叶变换，并进行分析，最后输出图形。最简单的原创(Pulse Doppler radar, the received signal, fast Fourier transform, and analyze the final output graphics. The most simple and original)

对于胡良谋的书《支持向量机故障诊断及控制技术》中的各个例程，绝对有用(For Liang- Mou s book " support vector machine fault diagnosis and control technology" of the various routines)
