Reducing the peak-to-average power ratio of OFDM

VTC '98. 48th IEEE Vehicular Technology Conference. Pathway to Global Wireless Revolution (Cat. No.98CH36151), 2002
The distribution of the peak-to-average power (PAP) ratio of an OFDM signal is derived, showing that large PAP ratios only occur very infrequently. Because of this, PAP reducing techniques which distort the signal can be quite effective, since only a small fraction of the OFDM signal has to be distorted.

Peak-to-average power ratio in high-order OFDM

IEEE Transactions on Communications, 2001
Summary: The problem of Peak-to-Average Power Ratio (PAPR) of high-order Orthogonal Frequency-Division Modulation (OFDM) is considered. Using results on level crossing of random processes, an upper bound on the probability that the PAPR of an OFDM signal will exceed a given value is derived.

Peak to Average Power Ratio Reduction of OFDM Signal

2005 Annual IEEE India Conference - Indicon, 2006
High Peak to Average Power Ratio (PAPR) of the transmitted signal is a major drawback of Orthogonal Frequency Division Multiplexing (OFDM). In Selective Mapping (SLM) technique, input data is multiplied with different number of phase sequences prior to OFDM modulation. The OFDM sequence with lowest PAPR is selected and transmitted.

Analysis of the Peak-To-Average Power Ratio for OFDM/OQAM

2006 IEEE 7th Workshop on Signal Processing Advances in Wireless Communications, 2006
OFDM/OQAM is now a recognized alternative to conventional OFDM for the transmission of signals over multipath fading channels. Indeed with OFDM/OQAM an appropriate pulse-shaping can be introduced to fight against time and frequency dispersion. This paper focuses on a theoretical and experimental analysis of the peak-to-average power ratio (PAPR) for ...

Interleaved PC-OFDM to Reduce Peak-to-Average Power Ratio

2005
Parallel combinatory orthogonal frequency division multiplexing (PC-OFDM yields lower maximum peak-to-average power ratio (PAR), high bandwidth efficiency and lower bit error rate (BER) on Gaussian channels compared to OFDM systems. However, PC-OFDM does not improve the statistics of PAR significantly.
