Characteristics of Ricean K-factor in wideband indoor channels at 3.7 GHz

This paper presents propagation characteristics of the wideband MIMO channel based on indoor measurements. An accurate characterization of the K-factor is very important in design issues in indoor environments, especially for MIMO and broadband networks. We have performed measurement campaigns for the indoor wideband channel using the Band Exploration and Channel Sounding (BECS) system developed by ETRI at 3.7 GHz with 100 MHz RF bandwidth. Based on the measured data, we analyze the Ricean K-factor characteristics of the wideband indoor channel.
