kalman filter with state constraints lecture and example

阵列信号处理工具箱，完成maltab下的阵列信号处理(Array signal processing toolbox, complete maltab array signal processing under)

帝国主义竞争算法基本的流程都有，解决具体的问题可在代码上修改。(Imperialist Competition Algorithm)

1. 基于simulink搭建一个QPSK发送链路，QPSK调制信号经过了瑞利衰落信道，观察信号经过衰落前后的星座图，观察信道特性。仿真参数：信源比特速率为500kbps，多径相对时延为[0 4e-06 8e-06 1.2e-05]秒，相对平均功率为[0 -3 -6 -9]dB，最大多普勒频移为200Hz。(1. Based on simulink structures, QPSK sent a link, the Rayleigh fading channel after the QPSK modulation signal, were observed before and after signal after the decline of constellation diagram, observation channel characteristic. Simulation parameters: the source is 500 KBPS bit rate, relative multipath time delay of [0 8 e 4 e- 06-06 e-05] 1.2 seconds, the relative average power is [0-3-6-9] dB, most of the doppler frequency shift is 200 hz.)

说明：   用matlab仿真的xc = [1 1 1 1 1 1 1 1 1 1] 的fft时序幅频图形(simulation using Matlab xc = [1 1 1 1 1 1 1 1 1 1] fft timing frequency graphics)

说明：  NMF矩阵分解算法可用于高维数据分解和降维处理分析。(NMF matrix decomposition algorithm can be used for high-dimensional data decomposition and dimension reduction analysis.)

源码为在声发射定位中，针对平面定位提高定位精度，自己编写的定位算法(acoustic emission location)

说明：  在matlab中的仿真，SVPWM驱动一台永磁同步电机，可以运行，波形比完美。(The SVPWM drives the permanent magnet motor simulation by the matlab, already running through. the waveform of the simulink is good. )

用Matlab演奏经典曲目卡农、最炫民族风、青花瓷、新贵妃醉酒，很多歌曲都可以使用此方法(Using Matlab played classics Canon, and most unusual national wind blue and white porcelain, New Drunken Beauty, a lot of songs can use this method)
