A Wideband One-Ring MIMO Reference Channel Model for Non-isotropic Scattering Environments

摘要

In this paper, we propose a wideband one-ring multiple-input multiple-output (MIMO) reference channel model for non-isotropic scattering environments. The model is designed in such a way that the delay power spectral density (PSD) of the reference channel model is identical to a given delay PSD. Furthermore, closed-form solutions are provided for the temporal autocorrelation function (ACF), the two-dimensional (2-D) space cross-correlation function, and the frequency correlation function (FCF). Finally, numerical results are presented for the reference channel model. The proposed reference channel model is an important framework for the derivation of an efficient wideband MIMO channel simulator with given space-time-frequency correlation properties.
