Wideband MIMO channel measurements in indoor hotspot scenario at 3.705GHz

This paper presents multipath channel parameters acquiring from wideband Multiple-Input Multiple Output (MIMO) channel measurement at 3.705GHz carrier frequency. The wideband MIMO channel sounder was used to measure MIMO radio channel characteristics. The channel measurement campaign was performed in the Seoul rail-way station where is a representative indoor hotspot region of Korea. The measurement campaigns were 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 channel characteristics such as root mean square delay spread, maximum excess delay, angular spread of arrival and angular spread of departure are presented.
