Abstract
How to reduce the Peak-to-Average Power Ratio (PAPR) in Orthogonal Frequency Division Multiplexing (OFDM) signals has become one of the key problems in OFDM system. By analyzing the reason of high PAPR, a new nonlinear companding method is proposed to reduce the PAPR in this paper. Then we give the optimal value of the parameter in this scheme. At last, our simulation results confirm that the suggested scheme exhibits good performances in both time and frequency domains by comparing with other methods.
