Szukana fraza: [Abstract = "This periodogram matrix is used to construct the corresponding spectrum of the multivariate orthogonal multisine random time\-series \(synthesis\). Application of the inverse finite discrete Fourier transform to this spectrum results in a multivariate orthogonal multisine random time\-series with the predefined periodogram matrix \(simulation\). The properties of multivariate orthogonal multisine random process approximations obtained in this way are discussed. Attention is paid to asymptotic gaussianess."]
