【简　介】:This paper introduces a PAPR reduction technique for OFDM
that uses the same PAPR reduction weights over multiple OFDM bauds. The PAPR reduction weights are applied on each subcarrier in the frequency domain and are designed to either be fixed over a group of subcarriers (in addition to multiple bauds) or the weights are parameterized by time taps. The advantage of these methods is to simplify channel estimation by not destroying the channel frequency correlation (for weights fixed over
groups of subcarriers) or by increasing the effective length of the
channel to be estimated (for the weights parameterized by timetaps).
Simulation results show up to a 6.0 dB decrease in PAPR where PAPR is measured over an OFDM baud.
