Definition of efficient PAPR in OFDM
IEEE Communications Letters, 2005A high PAPR is a main drawback of OFDM. There are many methods for reducing the PAPR with an ultimate goal of reducing the PAPR as much as possible. It is shown that if, among other factors, the power efficiency-PAPR relationship of the power amplifier is also taken into account, then there exists a PAPR level for which the BER reaches a minimal value.

Unlike single carrier-frequency division multiple access (SC-FDMA), just combining discrete Fourier transform (DFT) spreading and filter bank multicarrier with offset quadrature amplitude modulation (FBMC-OQAM) results in only marginal peak to average power ratio (PAPR) reduction.

PAPR Reduction for 5G Waveforms
2018 6th International Conference on Wireless Networks and Mobile Communications (WINCOM), 2018In order to meet 5G mobile communication requirements in terms of data rate, high spectral efficiency and low latency and complexity, multicarrier modulation is being investigated as a part of 5G physical layer solutions. Filter Bank Multicarrier, Universal Filtered Multicarrier and Resource Block Filtered Orthogonal Frequency Division Multiplexing are

Papr Clipping United with Altered PTS to Lessen Papr in OFDM
2019 International Conference on Computer Communication and Informatics (ICCCI), 2019For lessening the trouble in OFDM of PAPR, a distinctive arrangement is projected with provision clipping, hadamard matrix and PTS. In original PTS, designing of the phase sequence is very difficult and these phase sequences are highly required during division of data into multiple sub blocks.

Comparison of PAPR in OFDM and FBMC/OQAM Using PAPR Reduction Methods
2021Though the multicarrier technique orthogonal frequency division multiplexing (OFDM) is generous in 4G technology, it suffers with spectrum leakage, inefficient spectrum, and high PAPR. In this paper, the 5G waveform—FBMC/OQAM PAPR—is compared with OFDM in terminologies of PAPR, and it is analyzed that FBMC/OQAM suffers with high PAPR than OFDM which ...
