Correlative coding with clipping and filtering technique in OFDM Systems [PDF]
, 2003 The major setbacks of Orthogonal Frequency Multiplexing (OFDM) is its peak-to-average power ratio (PAPR) and intercarrier interference (ICI). The occurrence of these factors restricts its application.

PAPR Distribution Analysis at the Output of Nonlinear PAPR Reducers
Journal of Signal and Information Processing, 2012 Nonlinear PAPR reducers, such as clipping and companding techniques, are some simple methods used to reduce the Peak-to-Average Power Ratio (PAPR). In this paper, assuming that the baseband OFDM signal is characterized as a bandlimited complex Gaussian process, we investigate the PAPR distribution of an OFDM signal when it is passed through a nonlinear
