Modulation Formats and Waveforms for 5G Networks: Who Will Be the Heir of OFDM?: An overview of alternative modulation schemes for improved spectral efficiency (2014, background): “Indeed, the spectral efficiency of OFDM is limited by the need of a cyclic prefix (CP) and by its large sidelobes (which require some null guard tones at the spectrum edges), OFDM signals may exhibit large peak-to-average-power ratio values [2], and the impossibility of having strict frequency synch”
Radio Over Fiber Link Design for Next Generation Wireless Systems (2010, background): “Using the fact that the complex envelope of the OFDM signal is approximately Rayleigh distributed for large , the probability that the PAPR exceeds a certain threshold is found by solving for the complementary cumulative distribution and for band-limited signals is given by [10]:”

An Overview: Peak-to-Average Power Ratio Reduction Techniques for OFDM Signals (2008, methodology): “In [6], it also has been shown that the statistical distribution of the PAPR of the OFDM signals is not so sensitive to the increase of the number of subcarriers.”
Performance analysis of deliberately clipped OFDM signals (2002, methodology): “Also shown in the figure is the analytical approximation of the complementary cdf of the PAPR without clipping obtained from [ 29 ].”

Peak-To-Average Power Ratio Reduction in OFDM Systems: A Survey And Taxonomy (2013, methodology): “Assuming that the OFDM samples are mutually independent, this probability can be given as [39], [40]”
Root-Raised Cosine filter influences on PAPR distribution of single carrier signals (2008, background): “It is shown that two different behaviors occur for RRC filters when PAPR is derived, depending on the roll off factor, greater or not than a value around 0.4.”
A modern extreme value theory approach to calculating the distribution of the peak-to-average power ratio in OFDM systems (2002, methodology): “It is demonstrated through simulation that these simple and well-justified expressions are as accurate as those of [2] and [3], and, like the results in [2] and [3], apply surprisingly well for uncoded and coded OFDM systems with only a modest number of subcarriers.”
