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 ...

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.

PAPR Reduction by Symbol Nulling
VTC Spring 2009 - IEEE 69th Vehicular Technology Conference, 2009As a multicarrier signal can exhibit large peaks in the time domain, the amplifier used to transmit the multicarrier signal must be highly linear, and thus expensive, to avoid non-linear signal distortion. To reduce the high peak-to-average power ratio, and hence to allow cheaper amplifiers, several techniques are described in the literature.

Soft decision PAPR reduction in OFDM
International Multi-Conference on Systems, Sygnals & Devices, 2012This work deals with problem of improving the peak-to-mean average power ratio (PAPR) of the orthogonal frequency division multiplexing (OFDM) signals. Clipping is simple and efficient way to overcome the large PAPR in OFDM systems ; however this technique results in bit error rate (BER) increasing in the receiver.

PAPR Analytical Characterization and Reduced-PAPR Code Allocation Strategy for MC-CDMA Transmissions
IEEE Transactions on Wireless Communications, 2011In this paper, an approximate analytical expression for the peak-to-average power ratio (PAPR) of a Multi-Carrier Code Division Multiple Access (MC-CDMA) signal is derived. Then, it is demonstrated that the PAPR of a MC-CDMA system employing Walsh-Hadamard (WH) codes can be suitably reduced by resorting to a judicious strategy for the allocation of the

BER Based OFDM PAPR Estimation [PDF]
2018 26th International Conference on Software, Telecommunications and Computer Networks (SoftCOM), 2018 High Peak-to-Average Power Ratio (PAPR) of the transmitted OFDM signal is a well-known major drawback of the Orthogonal Frequency-Division Multiplexing (OFDM), so the High-Power Amplifier (HPA) is therefore necessary to operate in its linear region, i.e. with large back-off between the operating input power and its saturation region, so introducing not

PAPR analysis in noncontiguous OFDM systems
Transactions on Emerging Telecommunications Technologies, 2016AbstractNoncontiguous orthogonal frequency‐division multiplexing (NC‐OFDM) is a modulation technique suitable for 5G communications. It achieves high spectral efficiency due to aggregation and modulation with nonzero data symbols of only nonoccupied spectrum resources (subcarrier blocks).

Correlatively Precoded OFDM With Reduced PAPR
IEEE Transactions on Vehicular Technology, 2016Correlative precoders have been proposed for orthogonal frequency-division multiplexing (OFDM) to provide either improved spectral sidelobe suppression, which yields very compact signal spectrum, or enhanced intercarrier interference (ICI) self-cancelation, which renders robustness against carrier frequency offset (CFO).
