Interference Analysis between Mobile Radio and Digital Terrestrial Television in the Digital Dividend Spectrum

This paper concerns the analysis of adjacent channel interference of the Long Term Evolution (LTE) mobile system operating in Digital Dividend into Digital Video Broadcasting – Terrestrial (DVB–T) system. Field measurements in the live LTE network have been conducted in order to define most significant scenarios and for each of these Protection Ratios have been quantified. Variable load on the LTE base station has been taken into consideration. Therefore Protection Ratios for the LTE base station in idle state, and fully dedicated mode have been calculated. Interference mitigation techniques have been review, and an effective deployment method has been proposed.
