A comparative analysis of techniques for PAPR reduction of OFDM signals

In this paper the problem of high Peak-to-Average Power Ratio (PAPR) in OFDM (Orhogonal frequency-division multiplexing) signals is studied. Beside describing three techniques for PAPR reduction, SLM (SeLective Mapping), PTS (Partial Transmit Sequence) and Interleaving, detailed analysis of performances of this techniques for various values of relevant parameters (number of phase sequences, number of interleavers, number of phase factors, number of blocks) depending on applied technique, is carried out, as well as comparison of this techniques, based on Matlab simulation results.
