A new companding scheme is proposed to reduce the Peak-to-Average Power Ratio (PAPR) of Orthogonal Frequency Division Multiplexing (OFDM) signals.The characteristics and performance of system with conventional and new companding scheme are compared.The proposed scheme is illustrated in detail and analyzed in terms of reducing PAPR
computational complexity and improvement in BER performance in OFDM system.Our simulation results confirm that the suggested scheme exhibits a good ability to reduce PAPR and can outperform with lower computational complexity than conventional companding scheme substantially.
