Abstract: In earlier papers, 2p-periodic spectral data windows have been used in spectral estimation of discretetime random fields having finite second-order moments. In this paper, we show that 2p-periodic spectral windows can also be used to construct estimates of the spectral density of a homoge-neous symmetric a-stable discrete-time random field. These fields do not have second-order moments if 0 < a < 2. We construct an estimate of the spectrum, calculate the asymptotic mean and variance, and prove weak consistency of our estimate.
