Correlation characteristics of 2-dimensional antenna array signals in a multi-cell environment

초록

In this paper, we analyze the 3-dimension spatial channel model (3D-SCM) over time and spatial domains. SCM is a realistic channel model for multiple-input multiple-output (MIMO) wireless communication systems since it is known to adequately represent the channel properties with respect to the antenna geometry and conditions of user equipments (UEs). We observe its autocorrelation properties over time and spatial domains as functions of the angle spread and the effective Doppler frequency. The results can be used for efficient design of transmission methods, such as beamforming and precoding using codebooks to fully utilize the channel characterstics of two-dimensional antenna arrays. © © 2015 IARIA.
