Abstract
A Novel PTS Scheme for PAPR Reduction of Filtered-OFDM Signals without Side Information
Highlights
Orthogonal frequency division multiplexing (OFDM) has been recognized as an effective waveform for wireless communications
In this paper, a novel partial transmit sequence (PTS) scheme is proposed for reducing the peak-to-average power ratio (PAPR) of filtered orthogonal frequency division multiplexing (f-OFDM) systems
The performance of the proposed PTS scheme is compared with other conventional PAPR reduction schemes
Summary
Orthogonal frequency division multiplexing (OFDM) has been recognized as an effective waveform for wireless communications. Various schemes have been proposed to solve the high PAPR problem, which can be divided into two main categories: Signal distortion schemes such as clipping and companding transform [5]. It has a limited effect on PAPR reduction and can lead to the OOBE problem.
