ABSTRACT
ABSTRACT:
Orthogonal frequency division multiplexing (OFDM) is a modulation technique that has proven able to deliver high data rates in fading channels. It has already been adopted by such standards as IEEE 802.11a and European DAB/DVB. One of the principle drawbacks of OFDM is a potential for a high peak-to-average power ratio (PAPR). A solution to this problem will be presented that not only reduces the probability of a high PAPR but also reduces the bit error rate using modified Repeat-Accumulate codes with iterative decoding and clipping.
