Hamming Simulation in Matlab

说明：  讲述的直接序列扩频通信系统从信号产生，发射，信道传输，接收整个系统的程序(this is matlab for DS_SS system)

说明：  数字滤波器的设计，它在数字信号处理的过程中有一定的影响！非常有用。(filter)

说明：  光子晶体光纤中空气孔分布均匀时，计算光子晶体光纤的模式有效折射率(The effective RI of the mode propagating in PCF)

rls自适应滤波算法实现，仿真结果是误码率曲线的比较(rls adaptive filtering algorithm, simulation results of bit error rate curve is relatively)

跟踪滤波方法：概率数据互联。封装性能好！(Tracking filter method: probabilistic data association. Package good performance!)

衰落信道参数包括多径扩展和多普勒扩展。时不变的多径扩展相当于一个延时抽头滤波器，而多普勒扩展要注意多普勒功率谱密度，通常使用Jakes功率谱、高斯、均匀功率谱。( The fading channel parameters include multipath spreading and Doppler spreading. The time-invariant multipath extension is equivalent to a delay-tap filter, while the Doppler spread should pay attention to Doppler power spectral density, usually using Jakes power spectrum, Gaussian, and uniform power spectrum.)

说明：  这是一个关于MATLAB编程的PDF文档，希望对大家学习MATLAB编程有所帮助。(This is a pdf about matlab progressing,I hope it will be useful to you!)

无刷直流电机数学模型及其控制系统，效果良好，控制精度高(Brushless DC motor mathematical model and its control system to good effect, high precision control)

内附MATLAB学习的基本知识和很多MATLAB程序设计知识，是学习MATLAB的必备手册。(Included learning the basics of MATLAB and a lot of MATLAB programming knowledge, is the essential guide to learn MATLAB.)
