Description: Partial transmit sequences (PTS) is a class of
distortless PAPR reduction techniques for OFDM systems.
However, the high complexity of PTS remains a problem. In [5]
the authors show that the PAPR reduction performance of PTS is
not as good as that of another distortless technique-selected
mapping (SLM) with the same computational complexity. To
alleviate this problem, a novel selected PTS (S-PTS) method with
low complexity is proposed. The main idea is based on selecting
part of the candidate signals the overall signals, so as to
make a better tradeoff between PAPR reduction and
computational complexity. Simulation results demonstrate that
the PAPR reduction performance of S-PTS is better than that in
SLM when their overall computational complexities are identical
