On the base of a simplest model of quasi-periodical modulation of the Gaussian field in k-space we perform a set of simulations to bring out a relation between the large-scale baryonic acoustic oscillations (BAOs) registered in 3D-power spectra (Fourier space) of matter perturbations and quasi-periodical components characteristic for radial (along line-of-sight) distributions of cosmological objects in configuration (comoving) space. Properties of the radial (1D-) distributions built from different central points are specially investigated. We apply suggested approach to a sample of spectroscopic redshifts z of the brightest cluster galaxies (BCGs) and show that results turn out to be quite consistent with the results of the simulations.
