  • Abstract
    The high peak OFDM signal out of the linear region of the power amplifier is compressed with fixed scale down ratio instead of clipping. The compressed signal is transmitted using the additional subcarrier and can be restored if the tone detector at the receiver indicates the presence of additional subcarrier. This method shows the better BER performance than the normal clipping method. And also the comparison in the view of throughput efficiency shows that the proposed method is better than SLM.
