Abstract
Interference Analysis between Mobile Radio and Digital Terrestrial Television in the Digital Dividend Spectrum
Highlights
Due to greater spectrum efficiency, switching to digital terrestrial TV broadcasting frees part of the UHF spectrum from 790 MHz to 862 MHz called “digital dividend”
Taking into account the power density spectrum load dependency of an eNodeB signal, the present paper aims to provide an effective contribution in the comparison of the Protection Ratio (PR) and Protection Distance (PD) results obtained from the field measurements with results obtained from the simulations [12,13,14], and results obtained from laboratory measurements [17,18,19,20,21,22,23]
The conducted, and in this paper presented, measurement results are part of a study conducted for a mobile operator
Summary
Due to greater spectrum efficiency, switching to digital terrestrial TV broadcasting frees part of the UHF spectrum from 790 MHz to 862 MHz called “digital dividend”. The theoretical analysis of co-channel interference between mobile system and digital terrestrial television has been presented in [6,7,8] This is followed by experimental studies based on Monte Carlo simulations, aiming to define co-existence thresholds. In [12] and [13], simulation analyses are carried out to estimate the adjacent channel interfering effects of LTE Base Station (eNodeB) and User Equipment (UE) on DVB-T receiver systems, through the computation of the correspondent Protection Distance (PD). In both works, the power density spectrum of LTE signals has been approximated using the spectrum Block Emission Masks (BEM) reported on the ETSI recommendations ETSI TS 136 104 V8.7.0 for LTE base stations.
