A Simplified Approach to Applying the 3GPP Spatial Channel Model

Abstract

This paper reports on a set of channel models that have been proposed for the evaluation of system concepts for the long-term evolution of third generation mobile communications systems. Conflicting requirements between simplicity of implementation and accuracy in reproducing the radio channel are presented, and the resulting modeling choices are discussed. The channel models have been derived by combining a spatial channel model with several different antenna arrangements that are envisioned to be typical for the systems in question. These antenna arrangements include both spatial separation of elements and polarization. The channel models are supplied as tapped delay lines with correlation parameters for simulating full MIMO channels of size up to 4times4
