Abstract
This paper presents a practical three-dimensional (3-D) outdoor channel model for multi-user distributed massive multi-input multi-output (MU-DMMIMO). As the dimension of the antenna and the distance between transmitter and receiver increasing, the elevation angles will be more challenge, especially at the cell edge. In this paper, the beam pattern is assumed in the proposed channel model instead of the spherical wave front assumption used in current 3-D channel models. These include the far-field effects were done jointly with azimuth and elevation angles in different appearance clusters with various times of elevation and azimuth angle of departure and arrival on both the time and array axes. In addition, their impacts on MU-DMMIMO at the cell edge are investigated via statistical properties including a measurement of the path-loss power control on the non-stationary model of the user at the receiver. It is demonstrated that the proposed 3-D channel model is more accurate in characterizing real propagation channel when users are handovers at the cell edge.
