LTE and Future DTV Compatibility Study in the UHF band in Nigeria

This paper presents a compatibility study between future digital television (DTV) and Long Term Evolution (LTE) in the UHF band using Nigeria as a case study. This is done by carrying out an adjacent interference analysis to evaluate the impact of LTE base station on DVB-T2 reception using SEAMCAT software. Results obtained from simulations suggest that deploying LTE in an adjacent band would result in interference. Introducing a 1MHz guard band reduced the interference by 64.76% when a single interferer is deployed and an average of 20.91% with multiple interferers at 5km separation distance between the DVB-T2 transmitter and receiver. Further increase in the frequency separation did not show any substantial reduction in interference probability. This implies that DVB-T2 may coexist with LTE in the case of a single base station when the receiver is not more than 5 km away from the transmitter but may not when a high density of LTE base stations are deployed in the coverage area of DVB-T2. Finally, recommendations were made and further studies were suggested regarding coexistence issues between LTE and DTV.
