摘要：
The plane wave assumption has been used extensively in wireless channel modeling for simplicity. However, when the plane wave model is applied to the massive multiple input and multiple output (MIMO) channel characterization, it is no longer suitable. In this paper, by using the geometrical channel parameterizations, the phase shift difference caused by the spherical wave for a large linear antenna array is investigated, and the Far Region Boundary of a Linear Massive Antenna has been proposed as a criterion to determine whether the user terminal is within the near field of this large antenna structure. Finally, by using ray-tracing method, the proposed boundary within which the propagation caused phase difference exceeds 22.5. is verified. The spherical wave model is necessary for the more accurate channel characterization.
