Multiple input multiple output techniques combined
with orthogonal frequency division multiplexing (MIMO-OFDM)
provide a promising approach for wireless systems. However, a
serious drawback of the OFDM system is the high peak-toaverage

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
