Peak-to-Average Power Ratio Reduction for OFDM Based on Dynamic Range Compression

Abstract : We present a peak-to-average power ratio (PAPR) reduction method for orthogonal frequency-division multiplexing (OFDM) or similar modulation schemes based on dynamic range compression and decompression. Initially, the decompressor was developed for compressed audio signals. With regard to OFDM, the greatest benefit of the method is that it can be easily adjusted to the system requirements and a tradeoff can be found between the PAPR gain and signal distortion. Practically, it requires no additional side information at the receiver. In a pilot experiment, we evaluate the method using four different metrics and give a brief interpretation of the obtained results.
