Ricean K-factor analysis of indoor channel measurements at 3.7 GHz

Abstract

This paper presents analysis results of the wideband MIMO channel based on indoor measurements. An accurate characterization of the K-factor is very important in design issues, 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 indoor channel.

“…However, most of these works were only investigated in simulation. Measurements were carried out to analyze Kfactors for indoor environment [8] and in the reverberation chambers [9]- [10]. In [11], the maximum likelihood method was used to estimate the K-factor in urban areas with high transmitter location.…”
