针对三个非相干QASK数字调制信号的空间谱估计程序(For three non-coherent digital modulation signals QASK spatial spectrum estimation procedure)

基于matlab小波去噪程序，已经测试好了，可以直接使用的，提供给需要的朋友们( this is study on wavelet)

说明：  整数规划分支定界算法matlab通用源程序 各参数的意义同matlab优化工具箱的线性规划函数linprog 调用前，输入参数要化成matlab的标准形式(Integer programming branch and bound algorithm matlab source general meaning of each parameter with the matlab optimization toolbox of linear programming linprog function call before the input parameters to the standard form into matlab)

该函数用于读取ecg信号，找到小波变换模极大序列.(This function is used to read the ecg signal, find the sequence of wavelet transform modulus maxima.)

希尔伯特变化的matlab实例，非常实用，而且已经测试通过了(Hilbert translation is used widely in signal areas. It has been considered as one of the most important tools.)

k均值算法，社区划分算法中经典算法，WSN中分簇也可使用该算法。(K-means algorithm, classic algorithms in community partition algorithm, clustering can also use this algorithm in the WSN.)

利用lqg进行飞机的闭环控制，包括反馈增益求取等。(by the use of lqg, we can find the close loop control of the aircraft.)
