“…Because of the benefits of LWT and the advantages of WHT, it is suggested to combine concatenated LWT and WHT with UFMC waveform (LWT-WHT-UFMC) in this study in order to increase the achievement of UFMC waveform, which is one of alternative waveforms to OFDM candidate to 5G. In order to compare the traditional OFDM, UFMC and LWT-UFMC, suggested by Ayvaz et al [16], waveform with the suggested LWT-WHT-UFMC waveform, computer simulation works are executed under additive white Gaussian noise (AWGN) and flat Rayleigh fading channel conditions. It is observed from the achieved simulation results that the suggested waveform has better attainment than the traditional OFDM, UFMC, and LWT-UFMC waveforms in both AWGN and flat Rayleigh fading channels.…”

A novel concatenated Lifting Wavelet Transform (LWT) and Walsh Hadamard Transform (WHT) with Universal Filtered Multi Carrier (UFMC) waveform is suggested as an alternative to Orthogonal Frequency Division Multiplexing (OFDM) waveform for the next generation wireless telecommunication systems in this paper. The suggested waveform is composed of LWT and WHT with UFMC waveform. Both the elimination the disadvantages of OFDM and the improvement the achievement of UFMC waveform, from the fifth generation waveform candidates, has been aimed with the suggested waveform. In order to verify the performance of the suggested waveform and compare with the traditional OFDM, UFMC, and LWT-UFMC waveform computer simulation studies are performed in additive white Gaussian noise and flat Rayleigh fading channel environments. The acquired computer simulation results exhibit that the achievement of the suggested waveform has better than the achievement of the traditional OFDM, UFMC, and LWT-UFMC waveform.

Summary In multicarrier visible light communication (VLC) systems, orthogonal frequency division multiplexing (OFDM) has attracted a lot of attention due to its high data rate, simple equalization, and resistance to intersymbol interference (ISI). However, high peak‐to‐average‐power ratio (PAPR) and Light Emitting Diodes (LED) nonlinearity have important effects on the performance of indoor VLC‐OFDM systems. Asymmetrically clipped optical (ACO)‐OFDM is a technique that waste spectral efficiency to transmit a single pole frequency division multiplexed signal over a single pole channel. In this study, a new ACO‐OFDM method based on lifting wavelet transform (LWT)‐ACO‐OFDM is proposed to restore this spectral efficiency and increase the performance of the ACO‐OFDM system. The performance of the proposed method is verified by computer simulation studies over additive white Gaussian noise (AWGN) channel and multipath optical channel for analytical and simulated bit error rate (BER) performance criterion. From the obtained simulation results, it is seen that the proposed method provides approximately 16‐dB SNR gain against the classic VLC‐OFDM, roughly 12‐dB Signal to Noise Ratio (SNR) improvement versus the Direct Current (DC)‐biased optical (DCO)‐OFDM, and nearly 6‐dB SNR enhancement against ACO‐OFDM on the additive white Gaussian noise channel. It is observed from computer simulation results that similar SNR gains are obtained in multipath optical channels.

SummaryThe wireless communication is an integral part of the human life, which has been evolved from first generation (1G) to fifth generation (5G) where prime emphasis is on the enhanced mobile broadband (eMBB), ultra‐reliable low latency communication (urLLC), and massive machine type communication (mMTC). Further, we are working towards the sixth generation (6G) network where microtechnology and nanotechnology will play a key role to provide worldwide coverage, increased spectral/energy/cost efficiency, and improved intelligence and protection. This paper emphasizes on the prime enabling technologies that are enabled by the microengineering and nanoengineering in 6G framework to meet these needs. Started with the detailed study and analysis of 6G networks such as evolution from 1G to 6G and prime difference between 5G and 6G. Further, the potential 6G dimensions, architecture of microtechnology and nanotechnology designs, and key techniques required in 6G networks are explored in detail. Moreover, the role of cognitive technologies for development of micro‐ and nano‐perspective in 6G networks is presented. Furthermore, after discussing about the application areas, finally, the prime research challenges and potential future research directions are illustrated.
