An Orthogonal Frequency Division Multiplexing and Universal Filtered Multi-Carrier System with Degraded Impulsive Noise Channel Analytical Bit Error Rate Performance Assessment

Abstract

In this era of IoT and Industry 4.0, the evolving ubiquitous networking infrastructure includes the WSN and PLC with 5G mobile communication technology to extend the network coverage to remote locations. In such heterogeneous integration, the end-to-end channel noise cannot be properly characterized by AWGN Noise, since the WSN and PLC networks are usually affected by non-white Gaussian noise like Impulsive noise. No studies have been conducted on how impulsive noise affects UFMC performance. In order to assess the BER performance of OFDM and UFMC multicarrier modulation schemes in the Rayleigh Fading environment, this paper took into account the existence and influence of impulsive noise. The Middleton Class a model for impulsive noise is used to model. The BER performance improvement is observed for UFMC over OFDM with the help of simulation. The finding encourages the deployment of UFMC in the PLC and WSN portion of the entire network which will also ensure the smoother and faster integration of these heterogeneous networks with lower BER. The improvement of the BER performance is observed when the numFFT is increased and QAM is reduced in UFMC. The best performance is achieved with numFFT=1024 and QPSK modulation on the impulse noise channel.
