Selected Mapping (SLM) [3, 4], Partial Transmit Sequences [5, 6], using codes with low PAPR code words [7, 8], clipping and filtering [9-12] and Active Constellation Extension (ACE) [13, 14]. One of the peak reduction methods is Tone Reservation (TR) [15, 16].

Due to this high PAPR, the amplified signal is distorted if its peaks are not controlled. Ochiai proposed an interesting shaping scheme for OFDM to reduce PAR.[ix] First, he introduced a trellis coding/shaping mechanism, where a convolutional coder generates valid code words that will code to 0 by the receiver's block coder.

In this method, some of the subcarriers of an OFDM frame are reserved for PAPR 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. In this work, we consider ourselves with the performance of the tone reservation in the probabilistic asymptotic setting. 802.11ax OFDMA. The IEEE 802.11ax introduced significant enhancements over the existing 802.11ac standard [ 2].One of the key improvements is the OFDMA, which is an extension of orthogonal frequency division multiplexing (OFDM) digital modulation technology into a multiuser environment. tone location, and scaled so that the power of the peak tone should be reduced to the desired target clipping level. But this operation affect the whole value of OFDM symbol in frequency domain, i.e., not only C but also X is changed.
