FBMC modulation as a possible co-existence facilitator for LTE mobile networks in 800 MHz band

Abstract

This paper proposes filter bank multicarrier transmission technique (FBMC) as means to minimize adjacent band interference from long-term evolution (LTE) user equipment operating in the frequency band 792 862 MHz to short-range devices in the band 863 870 MHz. Main FBMC benefits are presented through comparison with reference case of orthogonal frequency-division multiplexing. The key advantage of FBMC modulation in reported electromagnetic compatibility studies is derived from its low out-of-band leakage, which guarantees minimum harmful interference level between stations using adjacent channels. The problem was evaluated in two aspects: first, theoretical analysis using minimum coupling loss method, complemented with statistical Monte-Carlo analysis (using SEAMCAT software tool) in order to verify results obtained in theoretical approach.
