## Abstract High peakβtoβaverage power ratio (PAPR) is a critical issue in any orthogonal frequency division multiplexing (OFDM) system, such as digital video broadcasting (DVB). Due to the nonlinearity of high power amplifier (HPA), it can result in low power efficiency and performance degradation
## Abstract One major defect in orthogonal frequency division multiplexing systems is the high peakβtoβaverage power ratio (PAPR) at the transmitter. The linear nonsymmetrical transform (LNST) technique, one of the companding transform (CT) techniques for PAPR reduction, offers excellent performanc
