分别用Pisarenko谐波估计法、MUSIC算法和ESPRIT算法对三正弦叠加高斯白噪声信号源进行频率估计，附件中有代码说明，编译环境为matlab。-Respectively Pisarenko harmonic estimation, MUSIC algorithm and the ESPRIT algorithm superimposed on the three sine Gaussian white noise signal source for frequency estimati

kalman 卡尔曼滤波C代码 用于滤除高斯白噪声的滤波 测试真是可用。-The kalman Kalman filter C code for filtered white Gaussian noise filtering test is really available.

matlab方法去除高斯白噪声，比较全面，有效。很好用的代码(Matlab method to remove gaussian white noise, more comprehensive, effective. Very handy code)
