Abstract
Coexistence between IMT-Advanced system and existing digital broadcasting is a matter of considerable when operating in a same or adjacent frequency channel within the band 790-862 MHz, which is recently allocated for mobile IMTAdvanced Systems represented by LTE-Advanced system. This can cause intersystem interference that affects on the coexisting feasibility between LTE-Advanced and digital broadcasting Receiver. In this paper, an efficient, simplified and graphical scheme for spectral emission mask and interference power level is proposed to investigate different channel overlapping scenarios between the two systems. A range of significant factors such as bandwidth, propagation distance, losses due to clutter, and antenna discrimination losses that can affect on the compatibility feasibility of the two systems are employed. The results demonstrate that using co-channel may unworkable unless some intersystem interference mitigation techniques are applied.
