Abstract

A systematic procedure for a new approach to reducing the high Peak-to-Average Power Ratio (PAPR) of OFDM using turbo coding is described in this paper. Part of the produced symbol from the turbo coding process with low PAPR is sent instead of the original OFDM symbol, whilst the rest is sent through different antenna(s). This technique can support different types of modulation and coding techniques, and offers better results in both the CCDF and the BER than the conventional techniques currently proposed for this purpose, such as the clipping technique and the PTS technique, which presented by computer simulations.
