Özet
In this study, zero tail inverse Lifting wavelet transform spread fast Walsh Hadamard transformed OFDM (ZT-ILWTs FWHT OFDM) is recommended as an alternative to the OFDM waveform for the new generation of wireless transmission systems. The recommended waveform is composed of a combination of inverse Lifting wavelet transform (ILWT) and fast Walsh Hadamard transform (FWHT) with OFDM waveform. The proposed waveform is tested with computer simulation studies for bit error rate (BER), peak to average power ratio (PAPR) and out of band emission (OOBE) performance criteria. From the attained results, it is observed that the recommended waveform is better than classical OFDM and zero-tail discrete Fourier transform spread OFDM (ZT-DFT-S OFDM) waveforms for all three performance criteria. © 2020 IEEE.
