Multipath channel parameters based on indoor hotspot channel measurements at 3.7GHz

Statistical characterization of the indoor hotspot radio channel is very important for the future MIMO system design. In this paper, we present multipath channel parameters acquiring from wideband MIMO channel measurement at 3.7GHz, frequency hand. The channel measurement campaign has been performed in the Incheon international airport, where is a representative indoor hotspot region in Korea. The measurement was carried out at peak time and at off-peak time, respectively. Each measurement scenario includes both line of sight (LoS) points and non-line of sight (NLoS) points. The numerical results of MIMO channel characteristics such as root mean square delay spread, maximum excess delay, angular spread of arrival and angular spread of departure arc presented.
