This paper proposes a companding plan, where little signals are augmented and vast signs are diminished, to lessen the Peak-to-Average Power Ratio (PAPR). Simulation comes about demonstrate that the proposed strategy has a point of interest in any event when contrasted and the traditional strategies, i.e. improved PAPR. To reduce this PAPR we have many reduction techniques but most of the techniques have not considered both complexity as well as the main factor PAPR. Here a new combinative
