Abstract


The fifth-generation wireless mobile communication technology, which has already been released, represents a new progression. But for those who study and develop mobile communication technology, greatly increased data rates and the required mobility of new wireless applications have become difficult challenges. Great data rates, huge channel capacities, high quality, and a low Peak-to-Average Power Ratio are requirements for 5G wireless networks (PAPR). For 5G wireless communication networks, the Filter Bank Multicarrier (FBMC) technique is viewed as a potential solution.   The simulation shows that FBMC performs better than OFDM in terms of Bit Error Rate (BER). This study evaluated the presence and impact of impulsive noise. It is modeled using the Middleton Class A model for impulsive noise. With the use of simulation, the FBMC performance gain over Orthogonal Frequency Division Multiplexing (OFDM) is seen. The finding recommends the adoption of FBMC in the PLC and WSN components of the whole network, which will also guarantee the smoother and faster integration of these heterogeneous networks with reduced BER. Increased K and numFFT in FBMC result in an improvement in BER performance. Also decreased Quadrature Amplitude Modulation (QAM) in FBMC found good performance in BER. When using K=4, Quadrature Phase Shift Keying (QPSK) modulation, and numFFT=2048 on the impulse noise channel, the performance is at its finest.
