Tuning the ITU-R P.1546 model in a MIMO scenario and urban environment

Abstract

A possible scenario for the evolution of Television Broadcast is the adoption of 8 K resolution video broadcasting. To achieve the required bit-rates MIMO technologies are an actual candidate. In this scenario, this paper collected electric field levels from a MIMO experimental system for TV broadcasting to tune the parameters of the ITU-R P.1546 propagation model, which has been employed to model VHF and UHF broadcast channels. The parameters are tuned for each polarization alone and for both together. This is done considering multiple reception points and also a larger capturing time interval for a fixed reception site. Significant improvements on the match between the actual and measured link budget are provided by the optimized parameters.
