Ítem Analysis of coexistence and mutual interference between mobile and digital television systems(Universidad Icesi, 2011-10-01) Guiducci, Doriana; Grazioso, Paolo; Barbiroli, Marina; Carciofi, Claudia; Riva, Guido; Guidotti, AlessandroThe ever increasing demand for multimedia wireless communication systems is a key feature of more advanced markets. The buzzwords of personal communications, meant to provide “access to anyone, anywhere, at anytime to the wanted service”, implies that radio spectrum demands are dramatically increasing in most developed markets. The last World Radiocommunication Conference (WRC-07) allocated on a co-primary basis the upper part of the UHF band to mobile services as from 2015 in Region 1, taking advantage of the Digital Dividend due to the higher spectrum efficiency of digital TV with respect to the analogue system. This will cause potentially harmful mutual interference between TV and mobile radio services, that needs to be carefully analysed. In this paper we present a study of the co-channel interference problem, proposing a methodology to take into account the mutual interference between a LTE mobile network and a DVB-T system and highlighting the different behaviour of the two radio links.Ítem Transmisión de contenidos 3D sobre televisión digital (DVB)(Universidad Icesi, 2013-04-01) Navarro Cadavid, Andrés; Carlos Andredy, ArdilaDuring 2019, all transmission of analogical TV signals in Colombia will cease, favoring the new Digital Terrestrial Television [DTT] format. By then is to be expected that operators and audience had fully adopted this new technology, so its advantages and benefits could be fully exploited. After though examination and study, Colombian government has adopted the European standard DVB-T2 (Digital Video Broadcast - Terrestrial V.2), considering it the most capable to satisfy the local requirements and expectations. Several aspects and services of this standard are still being toughly discussed, 3D content broadcast is one of them, so those who possess appropriate devices, could enjoy high definition stereoscopic video, just as it can be seen in a 3D or IMAX movie theater. This paper explores planned or already developed solutions to this challenge. It runs over the available academic and commercial information, as it explains the basic principles and techniques that make this technology possible in the first place.
