Massive multiple-input multiple-output (MIMO) is a potential candidate key technology for the 5G of wireless communication systems. In research to date, different power loss and shadowing effects on different antenna elements across the large arrays have been neglected. In this paper, based on an idealized propagation model, a new large scale attenuation (LSA) model is proposed, by which the large...
This paper presents a multiple frequency bands-switching scheme for wideband channel sounding, which is able to extend the overall sounding bandwidth without changing operation bandwidth of the hardware. It is especially suitable for low mobility and high data-rate scenarios (e.g., indoor hot spot) in the fifth generation mobile communication systems. With this scheme, a channel sounder is developed...
