A new distribution bound and reduction scheme for OFDM PAPR

A new simple upper bound on the PAPR distribution of an OFDM signal is proposed and simulations show that it is tight when the subcarrier number is greater than 64. In addition, a PAPR reduction scheme named selective mapping-dynamic constellation (SLM-DC) is proposed. Simulations show this combination of SLM-DC achieves good PAPR reduction while it extends DC´s ability to reduce PAPR and has less computational complexity. The average power increase in SLM-DC is estimated by the proposed upper bound.
