Coexistence Between Dvb-T2-Lite And Lte Downlink Networks In Advanced Mobile Fading Channels - Partial Overlapping Rf Spectrum

This paper presents results from the study of coexistence between second generation digital video broadcasting terrestrial-lite (DVB-T2-Lite) and Long-Term Evolution (LTE) downlink networks in a shared radio frequency (RF) band. Partial overlapping coexistence scenarios are considered. A laboratory measurement testbed is used to measure the impact of interfering LTE system on DVB-T2-Lite system. To emulate T2-Lite mobile scenario, Vehicular Urban (VU30) and Motorway Rural (MR100) advanced fading channel models are used. Experimental results show that the DVB-T2-Lite performance, measured as dependences of Bit and Modulation Error Ratios on the carrier-to-noise ratio, is highly depending not only on the proportion of RF channel overlapping and bandwidth of the LTE signal, but also on conditions in the transmission environment.
