“…For example, when TR-TI-Flipping chose 13 and 26 as the numbers (L) of PRTs, the numbers (l) of candidate signals with TR would be 53 and 105, respectively. However, because the TR-TI technique yielded 2 separate candidate signals of 5 13 and 5, 26 the massive computation led to difficulties in computer simulation. Therefore, using the conventional TR technique, this study compared the PAPR-reduction efficiency of conventional TR and TR-TI-Flipping techniques in a SC-FDMA system.…”

“…However, although both orthogonal frequency-division multiple access and SC-FDMA have retained the advantages of OFDM, they have also inherited its weaknesses, one of which is the problem of a high peak-to-average power ratio (PAPR). So far, several countermeasures, such as the partial transmit sequence (PTS), 1-3 selective mapping (SLM), [4][5][6] tone reservation (TR), [7][8][9][10][11][12][13][14] block codes, 15,16 and tone injection (TI), 17,18 have been implemented to improve the PAPR. Both the PTS and SLM are types of the multiple signal representation technique.…”

SummaryThis paper proposes a new method for reducing the peak-to-average power ratio of the single-carrier frequency-division multiple access system. The method is an integration of the tone injection (TI) and tone reservation (TR) techniques.A recommended method that uses TI to improve TR's low data transmission rate problem that is caused by the reservation of subcarriers. Additionally, to reduce the massive amount of computation required by the combined needs of TI and TR, an iterative flipping algorithm was adopted for this purpose. Simulation results indicate that the proposed method is not only capable of effectively improving the peak-to-average power ratio-reduction efficiency of the single-carrier frequency-division multiple access system but it can also improve the data transmission rate of the conventional TR technique.

“…Thusly, OFDM has been used in various wireless benchmarks, to be specific, Digital Audio Broadcasting (DAB), Terrestrial Digital Video Broadcasting (DVB-T), IEEE 802.11a standard for Wireless Local Area Networks (WLAN) and the IEEE 802.16a standard [1,2]. A pivotal burden of the OFDM-based plan is its high peak-to-average power ratio (PAPR) at the transmitter, requiring the use of a linear amplifier that prompts to low power adequacy.…”

Abstract:The OFDM signals which have a broad peak-to-average power ratio is a basic prerequisite to be settled. The Orthogonal Frequency Division Multiplexing (OFDM) traces the Partial transmit sequences (PTS) which is one among the appealing procedures to diminish the peak-to-average power ratio (PAPR). An issue of modern computational multifaceted nature happens in The PTS scheme when prevalent quantities of sub blocks were consumed. In this article, another PTS scheme has been industrialized so as to decline the PAPR by picking the ideal stage factor esteem by means a versatile ABC optimization process. At the point when associated with MIMO-OFDM structures with a broad assortment of phase factors ABC based PTS calculation achieves about elite after simulation. It can essentially diminish the computational intricacy for bigger PTS subblocks and offers lower PAPR in the meantime. The anticipated philosophy is connected in the working stage of MATLAB and the utilitarian solutions were incited and researched.

“…In this article, two new methods are proposed to reduce PAPR in OFDM/OQAM systems: the overlapped scaling TR (OS-TR) method and the multi-kernel TR (MK-TR) method. These methods exploit the overlapping nature of OFDM/OQAM signals, and thereby exhibit better performances than the controlled clipping TR (CC-TR) and multi-block TR (MB-TR) methods in [19]. Given that adjacent data blocks in the OFDM/OQAM signals overlap with each other-because of the introduction of the filter bank-the OS-TR method scales the filtered clipping noise to produce the peak-cancelling signal, and all the influences of the associated data block overlap are taken into consideration when computing the scaling factors.…”

The tone reservation method is one of the most effective pre‐distortion methods for peak‐to‐average power ratio reduction in orthogonal frequency division multiplexing (OFDM) systems. Its direct application to OFDM systems with offset quadrature amplitude modulation (OQAM) is, however, not effective. In this paper, two novel TR‐based methods are proposed, specifically designed for OFDM/OQAM systems by taking into consideration the overlapping nature of OQAM signals. These two methods have different approaches to the generation of the peak‐cancelling signal. The first one (overlapped scaling tone reservation) generates the peak‐cancelling signal using a least squares approximation algorithm with possible adjacent symbol overlap; the second one (multi‐kernel tone reservation) generates the peak‐cancelling signal by using multiple impulse‐like time domain kernels. It is shown by simulation that, when used in OFDM/OQAM systems, the proposed methods can provide better performance than the direct application of the existing controlled clipping tone reservation method, and even outperform the multi‐block tone reservation method.
