In this paper, zero-tail discrete wavelet transform spread OFDM (ZT DWT-S OFDM) waveform is proposed as an alternative to 5th generation (5G) waveform enhancement studies. In order to verify the performance of the proposed method and compare with the conventional OFDM and zero-tail discrete Fourier transform spread OFDM (ZT DFT-S OFDM) systems, computer simulations were performed on AWGN and flat fading channels. The obtained simulation results show that the proposed ZT DWT-S OFDM method has better out-of-band emission (OOBE), peak to average power ratio (PAPR) and bit error rate (BER) performance than conventional OFDM and ZT DFT-S OFDM.trinfo:eu-repo/semantics/closedAccess5Gwaveform designdiscrete wavelet transformOFDMZT DWT-S OFDMConference ObjectN/AWOS:000511448500360N/A
