Abstract / Description of output
In this paper, based on the concept of the tapped delay line (TDL) structure, we first propose a new wideband multiple-ring multiple input multiple output (MIMO) channel reference model for macro-cell scenarios. It is shown that the proposed model can easily match any given or measured power delay profile (PDP) and has the ability to jointly consider the angle of arrival (AoA), angle of departure (AoD), and time of arrival (ToA). From the proposed model, we derive the closed-form expression of the 3-dimensional (3-D) space-time-frequency (STF) correlation function (CF) for each tap, considering the interaction of the temporal, spatial, and frequency correlations. Finally, based on the proposed reference model, a deterministic simulation model is then proposed.
