Interference analysis between analog TV (PAL-G) and LTE (E-UTRA) in UHF band

Implementation of Long Term Evolution (LTE) 700 in Indonesia is feasible given the fact of 700 MHz spectrum availability in certain geographical rural areas. Also known that the spectrum allocation is adjacent to Analog Television (ATV) frequency which using PAL-G systems. Thus, the interference analysis on coexistence between ATV and LTE to define the minimum requirement of protection distance and guard band has to be taken into account. Therefore, according to the allowable C/I (protection ration) between these two services, the exact requirement has been simulated using SEAMCAT (Spectrum Engineering Advanced Monte-Carlo Analysis Tool) software. Several scenarios in SEAMCAT between ATV and LTE such as different direction of link have been taken. As a result, ATV and LTE can operate without disturbing each other by having 20 MHz with geographical distance radius of 5 km, 15 MHz with radius of 10 km or 10 MHz with radius of 40 km. The result could be used as a guideline in making plan for the coexistence between LTE and PAL-G in UHF band.
