Integrating LTE Broadband System in PMR Band: OFDM vs. FBMC Coexistence Capabilities and Performances

Abstract : This paper focuses on the use of Long Term Evolution (LTE) broadband system in coexistence with currently deployed Professional Mobile Radio (PMR) communication systems. The coexistence capabilities are analyzed using of an LTE like based system with Orthogonal Frequency Division Multiplexing (OFDM) and Filter Bank MultiCarrier (FBMC) physical layers. Obtained results show that, in order to achieve the LTEPMR coexistence, we need to filter the synthesized OFDM signal. This filtering is made to protect the PMR (TETRA, TETRAPOL, TETRA TEDS standards, etc.) systems by reducing the sidelobes levels due the use of modulated OFDM scheme. On the other hand, the FBMC signal fits perfectly the LTE-TEDS harmful interference protection requirements starting from the minimum frequency offset allowed by the TEDS standard mask. This can be explained by the fact that a good frequency localization is achieved by the prototype filter used in the FBMC scheme
