Propagation model calibration for DVB-SH in terrestrial Single Frequency Networks

This article studies terrestrial propagation model calibration for DVB-SH networks. DVB-SH is the European standard designed to transmit multimedia content to mobile terminals using a hybrid satellite/terrestrial infrastructure. One important particularity of DVB-SH is that it allows the implementation of Single Frequency Networks, where every transmitter emits the same signal at the same frequency. This article analyzes two propagation models suitable to perform propagation calculations in urban areas and S band: Xia-Bertoni, and a model based on the Hata formulae adding a diffraction term calculated using the Deygout method. Two different methodologies to calibrate propagation models using measurements from more than one transmitter in a SFN are studied and compared.
