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 ...

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

Intelligent interleaver for PAPR reduction
2008 Second International Conference on Electrical Engineering, 2008In orthogonal frequency division multiplexing (OFDM) systems, one of the major problems to be tackled is high peak to average power ratio (PAPR). In this paper a PAPR reduction scheme for OFDM system is proposed that takes the advantage of the classification capability of learning vector quantization (LVQ) networks.

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

FBMC-OQAM PAPR Reduction Schemes
2020 International Conference on Information and Communication Technology Convergence (ICTC), 2020Peak to average power ratio (PAPR) is a major problem that affects the performance of multicarrier systems. Filter bank multicarrier with offset quadrature amplitude modulation (FBMC/OQAM) is one of modulation schemes that has raised the attention of researchers given its superiority in terms of spectral efficiency. As any other multicarrier modulation
