“…In the first section of the exhibited work, BER-SNR achievement of traditional OFDM, UFMC, LWT-UFMC [16,34], and the suggested LWT-WHT-UFMC waveforms are compared over AWGN channel. In this section of the work, the effects of Dolph-Chebyshev, Kaiser and Gauss windows, with is of 40 and 73 length, and is of 40 dB sidelobe attenuation, on UFMC waveforms are examined in QPSK and 64-QAM modulation.…”

“…In the second section of the demonstrated work, BER-SNR attainments of conventional OFDM, UFMC, LWT-UFMC [16,34], and the suggested LWT-WHT-UFMC waveforms over flat Rayleigh fading channel are compared. The impulse response of the channel belonging to the timedependent communication system with multi-path propagation characteristics can be written as:…”

“…The transmitter-receiver block design of the wireless telecommunication system employing the suggested LWT-WHT UFMC waveform is illustrated in Fig. 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.…”

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.

“…The authors in [36] made a comparative study on the suitability of a Walsh-Hadamard transformed (WHT) universal-filtered multicarrier (UFMC) system with classical OFDM and UFMC systems in terms of BER and SNR performance. The authors in [37] established improved performance of a double-tree complex wavelet transform (DTCWT)-based OFDM system in combination with the fast WHT (FWHT) and eliminated the drawbacks of the OFDM system.…”

Analytical Framework of CP-Free Multiuser OFDM System for Coordinated Multi-Point at mmWave

et al. 2021

In this paper, a coordinated multipoint joint transmission (CoMP-JT) framework at mmWave for a cyclic prefix (CP)-free multiuser OFDM wireless communication system is developed and analyzed. The aim is to provide high-quality service to cell-edge users; otherwise, the cell-users would suffer from significant signal degradation due to undesired interference. The impact of complex Hadamard transform with block diagonalization channel precoding for multiuser interference reduction and designed subcarrier mapping for out-of-band (OOB) reduction are investigated. In addition, the paper studied the input back-off-aided high-power amplifier for peak-to-average power ratio (PAPR) reduction and forward error correction channel coding for improved bit error rate (BER) for cell-edge users at mmWave frequencies. Moreover, signal-to-interference-noise ratio and ergodic achievable rate are estimated both in the presence and absence of CoMP-JT-based transmission technique to verify their significance in terms of transmitted power. Numerical investigations showed an OOB reduction of 312 dB, PAPR reduction from 17.50 dB to 7.66 dB, and improved BER of 1×10−3 in 16-QAM for a signal-to-noise ratio of −6 dB. Hence, the simulation results demonstrated the effectiveness of the developed system.
