Peak-to-average power ratio versus instantaneous-to-average power ratio for OFDM
2008 42nd Asilomar Conference on Signals, Systems and Computers, 2008In the literature, peak-to-average power ratio (PAR) is often used as an indicator for the dynamic range of OFDM signals. PAR is an extreme value statistic and can present an overly pessimistic view of the signal. Instantaneous-to-average power ratio (IAR), on the other hand, reflects more accurately the characteristics of the sample population.

Peak-to-Average Power Ratio of OTFS Modulation
IEEE Communications Letters, 2019In this letter, we analyze the peak-to-average power ratio (PAPR) of orthogonal time frequency space modulation (OTFS) waveform. Towards this, we consider modulation symbols on an $N\times M$ delay-Doppler grid, where $N$ and $M$ are the number of Doppler and delay bins, respectively.

On the distribution of the peak-to-average power ratio in OFDM signals
IEEE Transactions on Communications, 2001Summary: The distribution of the peak-to-average power ratio (PAPR) in strictly band-limited orthogonal frequency-division multiplexing (OFDM) signals is studied. Assuming that the baseband OFDM signal is characterized as a band-limited complex Gaussian process, we first attempt to derive the exact distribution of the PAPR in the band-limited OFDM ...

DMT signals with low peak-to-average power ratio
Proceedings IEEE International Symposium on Computers and Communications (Cat. No.PR00250), 2003This contribution proposes a new family of methods to reduce the peak-to-average power ratio (PAR) in discrete multi-tone (DMT) and orthogonal frequency division multiplexing (OFDM) systems. This method avoids the use of extra inverse fast Fourier transformations (IFFT) as were used in some previously published techniques, but instead is based on ...

Methods for Peak to Average Power Ratio Reduction on SCFDMA
Proceedings of the SouthEast European Design Automation, Computer Engineering, Computer Networks and Social Media Conference, 2016Single Carrier Frequency Division Multiple Access (SCFDMA) is currently adopted by 3GPP in the LTE cellular systems for the uplink due to its high data rate and low peak-to-average power-ratio (PAPR). In this work, the PAPR for IFDMA (Interleaved Frequency Division Multiple Access), LFDMA (Localized Frequency Division Multiple Access), and DFDMA ...

Analysis of the Peak-To-Average Power Ratio of the Oversampled Ofdm
2006 IEEE International Conference on Acoustics Speed and Signal Processing Proceedings, 2006The oversampled OFDM modulation is a possible alternative to conventional OFDM for the transmission of signals over multipath fading channels. Indeed with oversampled OFDM, appropriate pulse-shaping can be introduced to fight against time and frequency dispersion.

On signals with very high peak-to-average power ratio
International Symposium onInformation Theory, 2004. ISIT 2004. Proceedings., 2004This paper address the problem of classification of BPSK-modulated multicarrier signals with the peak-to-average power ratio (PAPR) exceeding 3/4 of the maximal possible value. By providing a simple characterization of such signals, an upper bound on their number are derived and propose a simple sufficient condition for the signals to have low PAPR ...
