dc.description.abstractIn this article, a novel optical OFDM (LLWT Flip-OFDM) waveform based on Lazy Lifting wavelet transform (LLWT) is recommended to enhance the success of Flip-OFDM communication system, which is one of the optical OFDM methods used in visible light communication systems. In the proposed scheme, superior advantages of LWT transform such as ICI and ISI suppression capabilities because of its good time-frequency localization properties and orthonormal structure are utilized, unlike fast Fourier transform (FFT). In order to confirm the success of the proposed waveform through the bit error rate (BER) achievement benchmark, computer simulation studies are executed in the indoor multipath optical channel and underwater multipath optical channel environment. It is perceived from the acquired results that with the suggested LLWT Flip-OFDM communication scheme, 7.5 dB SNR gain is achieved against the Flip-OFDM communication system and 22.5 dB SNR improvement is performed versus the VLC-OFDM communication system.
