A novel companding transform is proposed to reduce Peak-to-Average Power Ratio (PAPR) of orthogonal frequency division multiplexing (OFDM) signals.This proposed technique can effectively reduce PAPR with low computational complexity.For practical applications
linear
nonlinear-symmetrical and nonlinear-quasi-symmetrical companding transform schemes are analyzed in terms of their companding effects
computational complexity
and improvement in BER performance in OFDM systems.It is shown by computer simulations that the proposed technique can outperform the conventional clipping-filtering scheme substantially.
