离散系统滑模跟踪的kalman应用，希望对大家有用(Sliding mode discrete-time systems kalman tracking applications, in the hope that useful to everybody)

说明：  提出了一种改进高阶Butterworth低通滤波器性能的设计方法。首先对高阶Butterworth低通滤波器的极点 进行重新分布，得出改进型Butterworth低通滤波器。性可以由其在基波电压初相位为零时的特性所唯一确定(Periodic voltage and current waveforms on the start time of its corresponding harmonic component of the relationship between the initial phase of research, pointed out that the characteristics of harmonic sources can be its initial phase in the fundamental zero-voltage characteristics of the CD a definite)

this is simple qpsk for matlab code

对qpsk一个整体的仿真，从源信号的生成，调制，加载波，解调等，步骤清晰，与通用教材原理图逐步仿真而来(Qpsk simulation of a whole, the signal generated from a source, modulation, plus carrier demodulation step clarity, and general simulation of materials gradually from the schematic)

ofdm系统设计，采用qpsk调制，可以轻松改变信道条件，比较研究，是非常方便的工具，我用了很多次了，很不错哦！！！(ofdm system using qpsk modulation, you can easily change the channel conditions, comparative study, it is very convenient tool, I use a lot of times, very good, oh! ! !)

matlab下KALMAN滤波算法工具箱,给大家共享(Matlab toolbox Kalman filtering algorithm to share!)
