Controlling Peak-to-Average Power Ratio in Orthogonal Frequency Division Multiplexing System
Journal of Engineering and Sustainable Development, 2013 A major drawback of Orthogonal Frequency Division Multiplexing at the transmitter side is the high peak-to-average power ratio (PAPR) of the signal. Conventional solutions for this problem are to use a linear amplifier ( or to back-off the operating ...

Partial Transmit Sequences for Peak-to-Average Power Ratio Reduction in Multiantenna OFDM
EURASIP Journal on Wireless Communications and Networking, 2008 The major drawback of orthogonal frequency-division multiplexing (OFDM) is its high peak-to-average power ratio (PAR), which gets even more substantial if a transmitter with multiple antennas is considered.

Peak-to-average power ratio reduction in interleaved OFDMA systems [PDF]
2015 IEEE International Symposium on Signal Processing and Information Technology (ISSPIT), 2015 Orthogonal frequency division multiple access (OFDMA) systems suffer from several impairments, and communication system engineers use powerful signal processing tools to combat these impairments and to keep up with the capacity/rate demands. One of these impairments is high peak-to-average power ratio (PAPR) and clipping is the simplest peak reduction ...
