ABSTRACT = {OFDM based waveforms are considered as the main part of the latest cellular communications standard (namely 5G). Many inherited problems
from the OFDM-Based LTE are still under investigation. Getting rid of the
out of band emissions is one of these problems. Ensuring low out of band
emission (OOBE) is deemed as one of the most critical challenges to support
development of future technologies such as 6G and beyond. Universal Filtered
Multi Carrier (UFMC) has been considered as one of the candidate waveforms for the 5G communications due to its robustness against Inter Carrier
Interference (ICI) and the Inter Symbol Interference (ISI). It is also a preferred
option because it is the most appropriate for low latency scenarios. In this
paper, a novel approach is proposed that makes use of modified Kaiser-Bessel
filter-based pulse windowing instead of standard Dolph-Chebyshev filter for
UFMC based waveform. The aim of proposing the new approach is to enable
the reduction of spectral leakage into nearby sub-bands. A comprehensive
study for the modified Kaiser-Bessel filters is performed and the results are
presented in terms of several Key Performance Indicators (KPIs). Based on
the results of the simulation, the UFMC Kaiser-Hankel window demonstrated
lower sidebands and better power spectral density, when compared with the
traditional Orthogonal frequency-division multiplexing (OFDM) and UFMC
as well as the normal UFMC Kaiser window. In addition, the real test for
the kaiser window with 5G waveform is lower OOBE than conventional 5G
waveform (CP-OFDM and UFMC). The OOBE reduction of 31% of the
Kaiser vs. the Dolph-Chebyshev filter, 68% of Kaiser Hankel over the DolphChebyshev, and 20% of Kaiser Hankel over Kaiser filter have been reported
in this paper. The Power Spectral Density has been improved accordingly.},
