Description
Filter bank multi-carrier (FBMC) modulation in the visible light
communication (VLC) system is one of the most promising modulation
systems in optical wireless communications (OWC), especially in 5G and 6G
future applications. FBMC has a wide bandwidth compared to other
modulation systems. One of the highest degree essential conditions for
utilising the signal in VLC is that the signal is real positive, the signal is
agreeable with intensity modulation/direct detection (IM/DD), where
Hermitian symmetry (H.S) is utilised to get a real signal (RE) and to be
unipolar direct current (DC)-bias is used. Here the challenge arises as this
method increases complicating, due to the modulation of the N number of
frequency symbols, these symbols need 2N inverse fast fourier transform
(IFFT) and fast fourier transform (FFT), in addition to energy consumption.
This research focused on the time domain and not the frequency domain by
using the traditional complex FBMC generation signal, and to obtain the RE
signal by placing the RE signal side by side with the imaginary signal (IMs)
in a row, and then using new Flip-FBMC technology, which saves more
energy. The proposed technologies provide approximately 57% of the
number of IFFT/FFT. The use of Flip-FBMC technology consumes less
energy than traditional technologies with better bit error rate (BER)
performance.
