Abstract : High Peak to Average Power Ratio (PAPR) is the major disadvantage in Orthogonal Frequency Division Multiplexing (OFDM). OFDM is extensively used in wireless communication systems due to its excellent performance. To reduce high PAPR, various techniques like clipping, companding, coding, etc. have been proposed. Companding technique effectively reduces the PAPR. In this paper, we propose new non-linear companding transforms which reduce PAPR efficaciously and are much more flexible when compared to other existing transforms. The theoretical analysis and simulation results of the proposed scheme are presented. © 2013 Springer-Verlag.
