This proposed method reduces the peak-to-average power ratio (PAPR) of multi-carrier transmission, by exploiting null-subcarriers. Compared with the Partial Transmit Sequence Simulated Annealing (PTS-SA) method, the proposed method yields better PAPR reduction performance while consuming the same computation complexity and less channel side information (CSI). The proposed method also demonstrates better bit-error-rate (BER) performance and much lower computation complexity than Null-Switching when CSI is available. Meanwhile, our method is compatible with the current commercial systems and can incorporate with most other PAPR-reduction methods (such as partial transmit sequences, selective mapping, tone injection, trellis shaping).
