Polarimetric properties and modeling of the power delay profile in large hall scenarios

Abstract

A full-polarimetric model of the power delay profile (PDP) is proposed in a large hall scenario and validated with polarimetric measurements of a large open hall radio channel under Line-of-Sight conditions at 1.3 GHz. The measured radio channels were processed by the high-resolution parametric estimator RiMAX to estimate both the polarimetric specular multipath components (SMC) and dense multipath components (DMC). The model of the full-polarimetric distance-dependent PDP was derived from which the depolarization mechanisms are presented. In addition, it is demonstrated that the room electromagnetics theory applies to our scenario across all polarization links. The validity of the proposed model is provided by the good agreement between the polarimetric data and models. The results of this contribution highlight the fact that a complete polarimetric description of all propagation mechanisms is desired in polarimetric radio channel models.
