  • Abstract
    Partial transmit sequence (PTS) provides attractive peak-to-average power ratio (PAPR) reduction performance in OFDM or MIMO-OFDM. However, it leads to prohibitively large computational complexity. A cooperative PTS (co-PTS) is proposed. In co-PTS, alternate optimisation and spatial subblock circular permutation are employed. Simulation results show that co-PTS can reduce computational complexity dramatically and achieve better PAPR reduction performance compared to ordinary PTS.
