Abstract :
This paper aims at the high Peak to Average Power Ratio (PAPR) problem, which will occasionally reach the amplifier saturation region and therefore result in signal distortion in OFDM system. By combining the improved C transformation (μ_law compression) and the Partial Transmit Sequence (PTS), we present a new method to modify the PAPR property of OFDM system. The simulation results show that the new scheme can get better improvement on PAPR property, compared with the two methods used separately. In addition, the improvement is obtained at the expense of a little BER property of OFDM system as well as a little calculation complexity.
