摘要

5G air interface system is expected to provide an efficient usage of system resources and available spectrum. Higher main-lobe and lower side-lobe power are keys to achieve its efficiency. Filter Bank Multi-Carrier (FBMC) has been actively investigated for years and capable to enhance current system. This paper aims to study and to simulate the spectrum performance of FBMC utilizing Mirabbasi-Martin filter with a variation of overlap factor g = 3, 4, 5, 6. The results are comparing between the bandwidth, main-lobe power and side-lobe power of FBMC and OFDM. The FBMC g=4 is giving the most optimum performance because it performs higher main lobe power at a comparable OFDM bandwidth. Subsequently, we conduct computational simulation in the practical case of mobile network operator working at 945 MHz-952.5 MHz. The results have indicated a significant bandwidth efficiency and lower side-lobe power outside the spectrum band allocation.
