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.

We find the best possible reduction of the PAPR and give one optimal information set that achieves this reduction. Interestingly, when using more than one information carrier, the smallest Designing Tone Reservation PAR Reduction Designing Tone Reservation PAR Reduction Andgart, Niklas; Ödling, Per; Johansson, Albin; Börjesson, Per 2006-03-09 00:00:00 Tone reservation peak-to-average (PAR) ratio reduction is an established area when it comes to bringing down signal peaks in multicarrier (DMT or OFDM) systems. When designing such a system, some questions often arise about PAR The tone reservation (TR) is one example of constellation shaping methods [10]. 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.

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. Simulation results validate that the ATR scheme offers better PAPR reduction performance and lower computational complexity than the conventional TR scheme. 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.

Besides, an efficient tone reservation technique is proposed by Tellado in to overcome those drawbacks, especially, in a large number of subcarriers. 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.
