Several high-speed wireless systems use Orthogonal Frequency Division Multiplexing (OFDM) due to its advantages. 5G has adopted OFDM and is expected to be considered beyond 5G (B5G). Meanwhile, OFDM has a high Peak-to-Average Power Ratio (PAPR) problem. Hybridization between two PAPR reduction techniques gains the two techniques’ advantages. Hybrid precoding-companding techniques are attractive as they require small computational complexity to achieve high PAPR reduction gain. Many precoding-companding techniques were introduced to increasing the PAPR reduction gain. However, reducing Bit Error Rate (BER) and out-of-band (OOB) radiation are more significant than increasing PAPR reduction gain. This paper proposes a new precoding-companding technique to better reduce the BER and OOB radiation than previous precoding-companding techniques. Results showed that the proposed technique outperforms all previous precoding-companding techniques in BER enhancement and OOB radiation reduction. The proposed technique reduces the Error Vector Magnitude (EVM) by 15 dB compared with 10 dB for the best previous technique. Additionally, the proposed technique increases high power amplifier efficiency (HPA) by 11.4%, while the best previous technique increased HPA efficiency by 9.8%. Moreover, our proposal achieves PAPR reduction gain better than the most known powerful PAPR reduction technique with a 99% reduction in required computational complexity.

“…Indispensability of employing such amplifiers in practical applications makes the PAPR reduction a compulsory process for the multicarrier signals prior to giving them to the amplifier input. With the intention of avoiding the nonlinear HPA‐based signal distortions, the researchers proposed varied methods for PAPR minimization such as tone injection (TI), 9 active constellation extension (ACE), 10 coding, 11 tone reservation (TR), 12 clipping and filtering, 13 selective mapping (SLM), 14,15 partial transmit sequence (PTS), 16,17 and interleaving 18 …”

“…In the aforementioned PAPR reduction procedures, 9–18 the SLM method frequently employed in diversified multicarrier systems in the literature comes into prominence due to its capability of reducing the PAPR of transmission signal in a very effective manner without leading to any degradation. Furthermore, being possessed of a flexible structure suitable for any modification ensures the SLM to be among the most preferred PAPR reduction procedures.…”

SummaryThe universal filtered multicarrier (UFMC), which has emerged as a product of the intensive studies carried out for developing alternative waveforms compatible with the oncoming fifth generation (5G) technology, has rapidly become one of the few waveforms considered seriously to be utilized in the next generation telecommunication systems due to its exclusive features. However, high peak‐to‐average power ratio (PAPR) problem specific to the multicarrier waveforms is waiting for researchers as the primary issue to be tackled in the UFMC waveform. To address this issue, an efficient PAPR reduction scheme called discrete cuckoo search algorithm‐based selective mapping (DCS‐SLM) is suggested in this paper. While creating the proposed DCS‐SLM scheme, in order to make the original CS algorithm suitable to be integrated into the conventional SLM method, a novel DCS algorithm was developed. Thanks to the related DCS algorithm, it becomes possible in the SLM technique to perform phase sequence optimization, which is a combinatorial optimization process that can be carried out in discrete space. It is clearly observed from the simulation results that the integration of our novel DCS algorithm to create a new PAPR reduction technique called DCS‐SLM leads to a remarkable performance improvement in the conventional SLM method due to the DCS‐based phase optimization through which the PAPR of UFMC signals are reduced to minimum levels.

“…However, the classical PAPR reduction techniques given in the literature cannot provide an efficient PAPR reduction performance in WOLA‐OFDM waveform due to its overlapping nature. Unlike the conventional OFDM where the adjacent symbols are independent, in WOLA‐OFDM, after the extension operation in each symbol, the adjacent symbols are overlapped from their extensions before the transmission process.…”

Weighted overlap and add-orthogonal frequency division multiplexing (WOLA-OFDM) is a new waveform proposed recently for meeting the requirements of fifth generation (5G) telecommunication standards. In spite of being a serious 5G waveform candidate, WOLA-OFDM is exposed to the problem of high peak to average power ratio (PAPR) similar to the other waveforms in which multicarrier transmission strategy is employed. Due to the overlapping nature of WOLA-OFDM waveform, where the extension of the current symbol is overlapped with the extension of the previous symbol, it will not be efficient to apply conventional PTS (C-PTS) directly to the WOLA-OFDM waveform. Therefore, in this paper, we propose dual symbol optimization-based partial transmit sequence (DSO-PTS) technique for PAPR reduction in WOLA-OFDM waveform. In our proposed technique, two adjacent symbols are jointly considered when searching for the optimal data block with minimum PAPR unlike the C-PTS where the adjacent symbols are optimized individually. In the simulations, our proposed DSO-PTS technique, C-PTS, and GreenOFDM that is developed recently by modifying the conventional selective mapping (SLM) method are compared with each other with regard to PAPR reduction performance for different search numbers (SNs). In addition, the effects of DSO-PTS, C-PTS, and GreenOFDM on the amount of out of band (OOB) radiation in the power spectral density (PSD) graph of WOLA-OFDM employing solid state power amplifier (SSPA) is measured for different SNs and input back off (IBO) values. According to the simulation results, our proposed DSO-PTS technique clearly demonstrates a superior PAPR reduction and PSD performance.
