Description: Reduction of peak-to-average power ratio (PAPR) in
orthogonal frequency-division multiplexing (OFDM) system using
the partial transmit sequence (PTS) approach. In PTS, the total
search for the number of subblocks and the rotation factors must
be accomplished. As the number of subblocks and rotation factors
increases, PAPR reduction improves. The number of calculation
increases as the number of subcarriers increases, such that
complexity increases exponentially and the process delay occur
simultaneously. In this paper, a modified PTS scheme combined
with interleaving technique for PAPR reduction has been
presented. The scheme is very effective and avoids the use of any
extra Inverse Fast Fourier Transformations (IFFTs) as was done
in PAPR reduction by ordinary PTS technique when dividing the
various subcarriers into different subblocks. The simulation
result shows that PAPR performance is improved in comparison
with the modified PTS and computational complexity is reduced
