Coexistence of DVB-T2 and LTE in the 800 MHz band: Analysis of DVB-T2 System Configurations
Original language description
During the last World Radiocommunication Conference it was decided that the upper frequency parts of UHF bands (700 MHz and 800 MHz) shall be released for mobile services, provided by Long Term Evolution (LTE) system. This decision has caused coexistence issues between the 2nd generation digital terrestrial video broadcasting (DVB-T2) and the LTE systems. In this paper, the impact of LTE-downlink (LTE-DL) RF signals on the DVB-T2 system with different configurations is explored. The most important DVB-T2 parameter set, namely code rate, modulation, OFDM mode, guard interval and pilot pattern, applicable for portable indoor TV reception, are taken into account. In addition, possible IQ-imbalances are considered. Adjacent band coexistence scenarios (different LTE signal bandwidths and data loads) are assumed, according to the first digital dividend band frequency. Overall DVB-T2 system performance, influenced by LTE-DL, is evaluated by the protection ratio (PR) parameter. The obtained laboratory results extend the current state-of-the-art knowledge in this field and show that several DVB-T2 system options from the viewpoint of interfering LTE signal have an inconsiderable impact on the DVB-T2 system performance.
