Abstract-With the introduction of Digital TerrestrialTelevision (DTT) and the analogue television switch-off, terrestrial broadcast spectrum in the UHF band is being released for mobile communications, in particular for fourth generation (4G) Long Term Evolution (LTE) mobile services. This spectrum is known as digital dividend. An impending problem when deploying 4G LTE mobile networks in the digital dividend bands is that interferences may appear in the adjacent radio frequency channels used for DTT. In this paper, we analyze the adjacent coexistence of DTT and 4G LTE networks in the digital dividend bands at 700 MHz and 800 MHz. A generic framework is adopted such that results can be easily extrapolated to different scenarios and bands. Results are presented as a function of the guard band between technologies, for both LTE uplink and downlink adjacent to the DTT signals, and for fixed outdoor and portable indoor DTT reception. Also, the effect of using anti-LTE filters is studied.

Resumo-Este trabalho tem por objetivo analisar a interferência entre o sistema LTE (Long Term Evolution) e ISDB-TB (Integrated Services Digital Broadcasting Terrestrial version B) na banda de 700 MHz.Para a análise é determinada a distância mínima que assegura o funcionamento dos dois sistemas na gama de funcionamento. O impacto da interferência é avaliado em um cenário onde a estação de LTE, estação de TV digital e receptor de TV digital estão presentes na mesma área de cobertura.Usando os parâmetros apresentados neste trabalho é calculado a potência de interferência que chega ao receptor de TV digital de acordo com a distância da estação de LTE e receptor de TV digital.Além disso, o resultado também mostra que o filtro utilizado no receptor atenua a energia do sinal de LTE, e a distância entre a estação e o receptor de TV digital LTE diminui consideravelmente, o que permite uma interação entre os sistemas.Palavra Chave-LTE, 4G, ISDB-TB, Interferência, 700 MHz. Abstract-This work aims to analyze the interference between the LTE system (Long Term Evolution) and ISDB-TB (Integrated Services Digital Broadcasting Terrestrial version B) in the 700 MHz band.For analysis, the minimum distance is determined which ensures the operation of two systems in the operating range. The interference impact is evaluated in a scenario where the LTE station, digital TV station and digital TV receiver are present in the same coverage area. Using the parameters addressed in this paper, the interference power which arrives at the digital TV receiver is calculated according to the distance between the LTE station and the digital TV receiver.Furthermore, the result also shows that the filter used in the receiver attenuates the energy of LTE signal, and the distance between the station and the LTE digital TV receiver decreases considerably, permitting an interaction between the systems. Index Terms-LTE, 4G, ISDB-TB, Interference, 700 MHz.

“…Results from simulations prove that the broadcast data rate is highly dependent on the separation distance between the DTV receiver and the LTE eNodeB. Influence of DVB-T system on the LTE system performance below 700 MHz at different distances between the two transmitters and different offset distances is investigated in [20,21]. For the evaluation of the obtained results an adjacent channel interference ratio (ACIR) was used.…”
