kalman滤波器的使用，对于学习kalman有很大的帮助。(kalman filter)

第三章：数据预处理，将不规则分布的测网经过插值转换为规则网的处理。(Chapter III ：data preprocessing，Converts irregular distribution of measuring net after interpolation rule network processing.)

code for ferequency responce

说明：  采用matlab产生信号波形，实现QPSK编码。(Waveforms generated by matlab to achieve QPSK encoding.)

很好的matlab/simulink电子书(ebooks on matlab/simulink)

NMF常用源码。需要的拿去。NME常用MATLAB源码。(NMF common source. Need to take. NME used MATLAB source.)

使用高阶累积量对MPSK信号进行调制识别，可实现对二维数据的聚类，迭代自组织数据分析。( Using high-order cumulants of MPSK signal modulation recognition, Can realize the two-dimensional data clustering, Iterative self-organizing data analysis.)

this file consists of the turbo code in the AWGN channel. the simulation will nearly take 20 min to simulate but it will produce an excellent output with reaching the Shannon s limit exactly at 0.5db.

用标准粒子群算法对PID控制器参数进行整定优化，效果理想(The standard particle group algorithm of PID controller parameters optimization setting, ideal effect )
