Description: dct precoded SLM method for PAPR reduction
High Peak to Average Power Ratio (PAPR) is still a
most important challenge in Orthogonal Frequency Division
Multiplexing (OFDM) system. In this paper, we propose a
Discrete Cosine Transform (DCT) precoding based SLM
technique for PAPR reduction in OFDM systems. This
technique is based on precoding the constellation symbols with
DCT precoder after the multiplication of phase rotation factor
and before the Inverse Fast Fourier Transform (IFFT) in
SLM-OFDM System. Platform: |

Description: Selective mapping algorithm is proposed to reduce the peak-to-average power ration (PAPR) in MIMO-OFDM system.
It is proved that the conjugate symbols on two antennas have the same PAPR property with orthogonal space-time block coded (STBC). By using the characteristic, the computational
complexity cost and the side information (SI) is significantly
reduced compared with the concurrent SLM algorithm.
Simulation results demonstrate that the performance of the proposed algorithm outperforms the conventional concurrent
SLM algorithm. Platform: |

Description: In this paper, we present a Selected Mapping (SLM) PAPR reduction technique for MIMOOFDM
system with special protection of Side Information (SI). Selected Mapping (SLM)
is a powerful PAPR reduction technique since it does not cause any signal distortion and
simple to implement. As a special protection for the Side Information (SI) of SLM technique,
we propose a SI power allocation procedure. Simulation results show that our proposed
technique gives significantly better BER performance than the ordinary SLM technique for
MIMO-OFDM systems. Analysis for the optimum SI power allocation is also presented. Platform: |

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-Partial transmit sequences (PTS) is a class of
