Channel capacity model in urban areas at 20–70 GHz for 5G systems

ABSTRACT

In this paper, a millimeter-wave (mm-W)–multiple-input multiple-output (MIMO) channel model is introduced for the fifth-generation (5G) of microcellular communication systems. This deterministic channel model is based on reflection phenomena, which is a dominated propagation mechanism at mm-W communication systems. The model analyzes the channel capacity (CP) based on some important factors including frequency, absorption atmosphere, polarization, materials of surfaces and distance between the transmitter and the receiver. Four urban scenarios are considered in the analyses which are based on real urban constructions. Finally, Measurement data that have been conducted on the other work validate the theoretical analysis and demonstrate that the proposed model can be used to predict CP in urban areas for 5G systems.
