A novel waveform design based on lifting wavelet transform for the 5G beyond

In this paper, a new waveform design based on Lifting Wavelet Transform (LWT) is proposed for next generation wireless communication systems. The proposed waveform design (LWT-UFMC) consists of combination of the LWT and universal filtered multi carrier (UFMC) waveform. It is aimed to improve the performance of the UFMC waveform, which is from the 5th Generation (5G) waveform candidates, with the proposed LWT-UFMC waveform. Computer simulation studies are performed to test the achievement of the recommended waveform and to compare with the classical OFDM and UFMC in AWGN and flat Rayleigh fading channels. It is seen that the proposed waveform from the obtained simulation results has the best and highly satisfactory performance. © 2019 IEEE.
