...Moreover, various approaches also have been proposed to reduce the PAPR including clipping [11]–[14], coding schemes [15]–[21], phase optimization [22], [23], nonlinear companding transforms [24]–[29], Tone Reservation (TR) and Tone Injection (TI) [30], [31], constellation shaping [32]–[34], Partial Transmission Sequence (PTS) and Selective Mapping (SLM) [35]–[51] and other techniques such as pre-scrambles proposed in [52]....
