sample number

Mapping ordered eigenvalue points of sample covariance matrix of the observation data onto Hough parametric space, the number of eigenvalues of noises can be estimated by detecting the peak points on Hough parametric space, and thus the number of signal source is determined.

该方法通过Hough变换将观测数据的采样协方差矩阵的排序特征值点投影到Hough参数空间，通过检测Hough参数空间中积累的峰值来估计噪声特征值的数目，从而确定信源的个数。
