Tone Reservation Technique Based on Peak-Windowing Residual Noise for PAPR Reduction in OFDM Systems Abstract: Peak-to-average power ratio (PAPR) of orthogonal frequency-division multiplexing (OFDM) may be reduced by reserving several tones to generate a peak-canceling signal (PCS). This method is called Tone Reservation.

In TR based schemes, there is no speciﬁc PAPR reduction information that needs to be Tone Reservation is one technique in which a small set of subcarriers are reserved for Peak Cancellation Signal.
This bounding technique also demonstrates that, applied to an ADSL-like system, the tone reservation approach could be used for

Tone reservation techniques use unavailable or reserved tones to design a peak-cancelling signal that lowers the PAR of a transmit data block.
These techniques have been shown to reduce the PAR for real-baseband OFDM signals, such as for ADSL. Our fast-converging real-baseband tone-reservation approach based upon active-set methods is extended to reduce PAR in complex-baseband signals. This new technique converges very quickly toward a minimum-PAR solution at a low cost.

Actually, the other PAPR reduction scheme needs the signaling overhead. For example, SLM and PTS need some Tone Reservation as a PAPR reduction technique version 126.96.36.199 (2.29 KB) by Baher Mohammed PAPR (peak to average power ratio) is a major problem that faces all OFDM systems. A Study on the Tone-Reservation Technique for Peak-to-Average Power Ratio Reduction in OFDM Systems: Author: Umer Ijaz Butt: Publisher: Universal-Publishers, 2010: ISBN: 159942360X, 9781599423609 : Export Citation: BiBTeX EndNote RefMan We improve the tone reservation (TR) technique by employing sliding window for the PAPR reduction of FBMC-OQAM signals, called sliding window tone reservation (SW-TR) technique. The proposed SWTR technique uses the peak reduction tones (PRTs) of several consecutive data blocks to cancel the peaks of the FBMC-OQAM signal inside a window. The classical Tone Reservation (TR) technique calculates a correction signal in an iterative way to reduce the amplitude peaks. However this step leads to a high computational complexity.
