The user traffic volume in the cellular network has been growing rapidly. Recent capacity enhancement techniques based on the small-cell architecture are examined for crowded areas such as urban railway stations and environs. Although small-cell propagation environments are characterized by short distances and low antenna heights, the applicability of current MIMO channel models in those environments...
In recent years, MIMO channel models for the crowded areas such as indoor offices, shops, and outdoor hot spot environments have become a topic of great interest. In the crowded environments, the propagation paths are blocked frequently by users walking around the mobile terminal, and it causes severe shadowing and fading of channel. In this paper, to take the impact of pedestrians on the channel...
Over the Air (OTA) measurements based on Spatial Channel Emulator (SCE) have attracted attention for evaluating the practical performance of MIMO user equipment (UE) for LTE and IMT-Advanced systems. In SCE-based OTA, the channel models and scenarios can be simulated in an anechoic chamber by controlling the transmit probe antennas placed around the UE. Recently, channel models that consider time...
