Peak-to-Average-Power-Ratio (PAPR) reduction in WiMAX and OFDM/A systems [PDF]

open access: yesEURASIP Journal on Advances in Signal Processing, 2011
A peak to average power ratio (PAPR) reduction method is proposed that exploits the precoding or beamforming mode in WiMAX. The method is applicable to any OFDM/A systems that implements beamforming using dedicated pilots which use the same beamforming ...

A Novel partial sequence technique based Chaotic biogeography optimization for PAPR reduction in generalized frequency division multiplexing waveform [PDF]

open access: yesHeliyon, 2023
For Orthogonal Frequency Division Multiplexing (OFDM) systems, the most significant problem is the peak-to-average power ratio. The utilisation of partial transmission sequence, often known as PTS, is an efficient method for reducing PAPR.
