In this paper, we point on the Peak-to-Average Power Ratio (PAPR) reduction for the uplink SC-FDMA system. Firstly, the conventional Tone Reservation (TR) is

High Peak to Average Power Ratio (PAPR) is a main area of concern in multi-carrier signals like Orthogonal Frequency Division Multiplexing (OFDM) modulated signals and several techniques have been devised to reduce PAPR. One of these PAPR reduction techniques is 'Tone Reservation' where PAPR is reduced by adding tones to the useful data tones to reduce the temporal signal's peak.

These techniques have been shown to reduce the PAR for real-baseband OFDM signals, such as for ADSL. Tone Reservation (TR) is a technique proposed to combat the high Peak-to-Average Power Ratio (PAPR) problem of Orthogonal Frequency Division Multiplexing (OFDM) signals. However conventional TR suffers from high computational cost due to the difficulties in finding an effective cancellation signal in the time domain by using only a few tones in the frequency domain. It also suffers from a high The reservation had a total 2000 census population of 10,787. The reservation has a land area of 11,243.098 square kilometres (4,340.984 sq mi), 97.48 percent of the Tohono Oʼodham Nation total area. The reservation encompasses portions of central Pima, southwestern Pinal, and southeastern Maricopa Counties. Tone Reservation (OS-TR) method generate the peak cancelling signal by considering the least square approximation algorithm with possible adjacent symbol overlap.

To enhance the power efficiency of high-power amplifiers (HPAs) with the demand of reducing energy consumption, a tone reservation (TR) technique is adopted to make orthogonal frequency-division multiplexing (OFDM) signals less sensitive to nonlinearity of HPAs. 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.
