DTT performance degradation in presence of coexisting LTE network interference

This paper investigates the Digital Terrestrial Television (DTT) performance degradation in presence of interference from the Long Term Evolution (LTE) mobile services operating in adjacent frequency band. The simulated DTT performances reveal the importance of the coexistence analysis between the LTE and the DTT networks. The proposed methodology investigates the degradation of the DTT service reception taking into account the aggregate LTE interference effects on the DTT systems that operate in the upper part of the DTT band. The relevant evaluation metrics are: the percentage of affected pixels (locations) and the probability of service degradation taking the territory of the Republic of Macedonia as evaluation area. The obtained simulation results identify the most critical locations that might require interference management, in order to ensure an acceptable TV service quality.
