In the paper the novel noneigenvector approach which uses the special power basis is presented. The persymmetry property of the data covariance matrix is used. The ways of calculation of the threshold between signal subspace and noise subspace eigenvalues of sample covariance matrix without calculation of the spectral decomposition of data CM are considered. The performance of the proposed approach is verified by computer simulation. Some computer simulation results are presented.
