“…PAPR is reduced by applying the windowing and clipping PAPR method to the OFDM structure. 12 The simulation results reveal that the proposed method accomplished a PAPR of 8 dB at a threshold of 0.7. Hence, the technique achieved a gain of 3 dB as compared to existing algorithms.…”

Non-orthogonal multiple access (NOMA) is a great contender for future cellular modulation due to its desirable properties like massive connectivity, high data rate transmission, and high spectral efficiency. However, its peak-to-average power ratio (PAPR) is significant, which becomes a significant disadvantage for the efficient operability of the NOMA waveform compared to current techniques. Several PAPR reduction algorithms like selective mapping (SLM), partial transmission sequence (PTS), and companding techniques have been proposed to lower the PAPR of multicarrier waveforms (MCWs). PTS reduces the PAPR but has high complexity. On the other hand, SLM has a less complex framework, but its PAPR performance is not as efficient as PTS. Companding methods reduce the PAPR by compressing the signals at the transmitter, which unfortunately reduces the dynamic range of the signal. In this work, we propose a hybrid algorithm (SLM + PTS) with a companding method for the first time for the NOMA waveform, which efficiently reduces the PAPR with low computational complexity. Furthermore, we compare the performances of a host of candidate algorithms like SLM, PTS, hybrid (SLM + PTS), hybrid + A law (SLM-PTS-A law), and hybrid + Mu law (SLM-PTS-Mu law). The results of the experiments show that the hybrid + Mu law did a better job than the existing PAPR reduction algorithms.

“…Power efficiency and low BER is the high demand in the field of communication that requires high data rates, large BW, low congestion [1]. Multi carrier OFDM is the solution for 4G technologies and beyond 4G techniques like 5G or beyond 5G communications that provide high-speed secured data transmission [2]. Single carrier system is the oldest way in the field of transmission of data that compromising with distortion of signals and high cost of frequency selection.…”

OFDM is one of the important modulation techniques for wireless communication which is the advanced version of FDM. Now-a-days congestion networking is growing like AI, IoT, 5G etc. so there is a need of high data rate with low BER. For such a network there is requirement of high-speed secured data transmission that is multicarrier technique OFDM. This modulation technique is useful for current and future scenario. One of the major issue in OFDM is high PAPR and this is happened due to large amount of input data bits. High PAPR results in distortion in bands and power inefficiency using power amplifier. RCF is the technique used in this paper to reduce the PAPR and analyze the results with and without applying PAPR reduction technique. In this paper, after application of 4 clip and filter SNR is improved along with decrement of CCDF of PAPR which is desired.

“…In addition, IoT needs to have a low power system, so we limit the real tests up to 5 W of average power. Different studies such as [28][29][30] show that OFDM IBOs are typical between 6 and 14 dBs. In Table 4, we can see the transmitted PAPR in terms of IBOs and the average power that is transmitted.…”

The number of Internet of Things (IoT) devices has experienced a large growth during the last decade, as well as the data volume gathered from remote sensors. Satellites are still a suitable communication method and may be preferable for a remote ubiquitous sensor network (USN), which sometimes are located in places without much communications infrastructure where coverage is the principal drawback. Alternatively, the proposed solution for this article aims at a near-vertical incidence skywave (NVIS) channel for high frequencies (HF) with a low-cost platform, allowing a low-power transmissions coverage area up to 250 km for USN. The HF standards are focused on generic communication channels not being robust for NVIS communications. In this article we study and test an alternative based on orthogonal frequency-division multiplexing (OFDM) modulations to make them more robust and less dependent on the channel NVIS communications. For that purpose, we test the HF standard modulations and a designed OFDM modulation to prove the robustness of each. This study has been tested between Barcelona and Tarragona, using different transmission power levels and modulation orders.
