“…Therefore, in the ZT FB‐S OFDM method, the power on the zero tails is suppressed using pulses in the form of raised cosine near the zero tails. Thanks to reduction of zero tail leaks it is obtained better bit error rate achievement, lower PAPR and out‐of‐band propagation performance than the ZT DFT‐S OFDM method with ZT FB‐S OFDM technique [33].…”

“…1 [34]. Although there are a few studies in the literature on the DWT‐OFDM [9–13], WHT‐OFDM [14,15], and alternative hybrid waveform [32,33], it is worth mentioning that there is no study that combines LWT and WHT with UFMC waveform. This proposed waveform is the first hybrid waveform structure, which is composed of LWT, WHT, and UFMC (LWT‐WHT‐UFMC) waveform.…”

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.

“…Also, different RC pulses with different roll-off factors can coexist orthogonally. It was proposed in [1], [22] to use pulses with high roll-off factors (low power tails) at the edges of the symbol and pulses with low roll-off factors (high power tails) in the inner part of the symbol. Here, we propose using the same concept with a different pulse shape.…”

The forthcoming communication systems are advancing towards improved flexibility in various aspects. Improved flexibility is crucial to cater diverse service requirements. This letter proposes a novel waveform design scheme that exploits axis warping to enable peaceful coexistence of different pulse shapes. A warping transform manipulates the lattice samples nonuniformly and provides flexibility to handle the time-frequency occupancy of a signal. The proposed approach enables the utilization of flexible pulse shapes in a quasi-orthogonal manner and increases the spectral efficiency. In addition, the rectangular resource block structure, which assists an efficient resource allocation, is preserved with the warped waveform design as well.
