A small number of subcarriers are reserved in transmitting to reduce PAPR. However, this algorithm also suffers large of FFT/IFFT operations due to large number of iterations. This method is called Tone Reservation. This method restricts the data vector X , and the peak reduction vector C to lie in disjoint frequency subspaces, i.e., X k =0, ki i ∈{, , } 1 L L and C k =0, ki i ∉{, , } 1 L L . In these approaches, tone reservation method constructs an additive PAPR reduction signal that uses a small subset of reserved subcarriers. These reserved tones are orthogonal with the data tones The key idea of the proposed ATR scheme is to iteratively perform the tone reservation (TR) scheme on the antenna with the maximum PAPR.

Tone Reservation technique has based on reserving some tones to reduce PAPR. The PAPR reduction amount depends on the number of the reserved tones and their position. The performance of TR also depends on the amount of complexity and reserved tones power. Tone reservation techniques use unavailable or reserved tones to design a peak-cancelling signal that lowers the PAR of a transmit data block.

Tone reservation uses other unused or reserved tones to design a peak-cancelling signal that lowers the PAR of a transmit OFDM block. In contrast to previous methods, the new active-set method proposed here converges very quickly toward a minimum-PAR solution at a lower computational cost.

Abstract—In this paper we propose a method for reducing nonlinearity distortion by limiting the envelope fluctuations of an OFDM signal. The method is based on tone reservation, and the free tones are assigned in a way to limit the variations of the instantaneous power of the time domain signal.

Tone Reservation mostly introduced in the next-gen television transmission system (DVB-T2) in the terrestrial domain.

We continue the theoretical contributions made by Boche and Farell towards the understanding of peak value reduction, using the strategy known as tone reservation for orthogonal transmission schemes.

There it was shown that for OFDM systems, the combinatorial object called arithmetic progression plays an important role in setting limitations for the applicability of the tone reservation method. 2010-07-23 In this letter, a novel adaptive tone reservation (ATR) scheme is proposed for the orthogonal frequency division multiplexing-based large-scale multiuser multiple-input multiple-output systems to deal with the inherent peak-to-average power ratio (PAPR) problem. The key idea of the proposed ATR scheme is to iteratively perform the tone reservation (TR) scheme on the antenna with the maximum In these approaches, tone reservation is considered as one of the most promising methods because of no additional distortion, no side information, and low implementation cost.
