Abstract :

This paper aims to analyze the impact of mutual interference between Long Term Evolution (LTE) and digital television (DTV) systems in adjacent channels in the 700 MHz band. During the analysis, minimum physical separation distances between the systems are determined to ensure their coexistence in this band. The interference impact is evaluated in a scenario where the DTV and LTE operate on channels 51 and 52 respectively. In order to obtain the results, this study was made using Monte Carlo simulations. Four classes of Digital Television were considered during the simulations: Special class, class A, class B and class C. The results show that the Special, A and B classes cause interference with the LTE, and the impact of such interference depends on the guard band and also the separation distance between the systems. Furthermore, the results also show that increasing the LTE bandwidth only has a greater impact if the LTE is the victim system. However, the coexistence of LTE and DTV in this band is possible once there is a minimum separation distance and an adequate guard band respected. methods .
