We propose a new companding scheme to reduce Peak-to-Average Power Ratio (PAPR) of Orthogonal Frequency Division Multiplexing (OFDM) signals to revise our previous work
which is based on our rigorous theoretical derivation.Both theoretical analysis and simulation results show that the proposed companding transform can reduce PAPR to below 7.8dB while keeping the average power unchanged
and the system having good BER performance simultaneously.
