The development and effective use of wireless communication systems to provide mobile services is rapidly increasing. Nowadays, the world´s most perspective standards to provide wireless multimedia services in high quality are LTE (Long-Term Evolution) and DVB-T2 Lite (DVB-2 nd Generation Terrestrial). On the other hand, these wireless multimedia systems can many times operate in a neighboring frequency spectrum. Therefore, as a result, numerous co-existence scenarios are possible. The focus of this paper is to explore and measure the co-existence between LTE and DVB-T2 Lite multimedia services.Theoretical backgrounds of the coexistence scenarios, general workplace and the principle of the measuring method of the influence of the LTE services on DVB-T2 services and vice versa are clearly presented and described. Furthermore, deeper investigation of the mutual influence of the DVB-T2 system on the LTE system is also explored and graphically illustrated. Finally, all obtained results are evaluated and future work is outlined.
Abstract-In this paper the influence of mobile network interfering products on DTV (Digital Television) services is explored and evaluated. More precisely, the overall aim of this paper is to measure and show the interactions between the mobile (GSM) and digital terrestrial television (DVB-T/H) broadcasting networks and services. In the DVB-T/H system configuration, the TPS (Transmission Parameter Signaling) carriers keep the receiver informed about the main system parameters. Disturbance of these carriers by interfering products of GSM network and degradation of DVB-T services are also explored and described. Theoretical backgrounds, general workplace and the principle of the measuring method is also introduced and briefly described. For the evaluation of the impact of mobile networks on the signal quality of DTV services the BER (Bit Error Ratio), MER (Modulation Error Ratio) ratios and constellation imperfections are used. Finally, the obtained results are evaluated and clearly described.
