Abstract

In this paper, we present a wideband one-ring multiple-input multiple-output (MIMO) channel model for non-isotropic scattering environments. The model is designed in such a way that the delay power spectral density (PSD) of the resulting reference channel model is identical to a given delay PSD. Furthermore, we present an efficient deterministic channel simulation model obtained by using the principle of deterministic channel modeling. The statistical properties of both the reference model and the simulation model are also studied. Analytical expressions will be presented for the temporal autocorrelation function (ACF), the two-dimensional (2D) space cross-correlation function (CCF), and the frequency correlation function (FCF). We show that the statistical properties of the deterministic simulation model can be brought into astonishingly good agreement with those of the reference model. The resulting deterministic simulation model enables the performance evaluation of wideband MIMO communication systems by simulation, which is shown exemplarily by studying the system performance of a space-time coded MIMO orthogonal frequency division multiplexing (OFDM) system.
