Modeling Multi-Frequency Characteristics for Classroom and Hall Scenarios at 2-4, 9-11 and 27-29 GHz Bands

This paper investigates the wideband channel characteristics obtained in a classroom and hall indoor scenarios at 2-4, 9-11 27-29GHz. A virtual uniform circular array (UCA) based sounding system was utilized to capture spatial characteristics. The propagation parameters of multipath components (MPCs) were estimated by using high resolution parameter estimation (HRPE) algorithm. MPCs are further grouped into clusters via novel clustering identification algorithm on KPowerMeans comparison composite cluster-level multiple frequency bands both is investigated. Moreover, impact room environment, i.e. dimension furniture, also analyzed. statistics extracted constitute stochastic clustered model.
