PAPR Reduction Based on Correction of Candidate Signals in PTS

摘要

Partial transmit sequence(PTS)is an effenciate technique to reduce peak-to-average ratio(PAPR)inorthogonal frequency division multiplexing(OFDM)system.But it has a high computational complexity.Toreduce the high complexity in PTS, a modified scheme,which is called Correction PTS(CPTS), is proposedbased on the correction among the candidate signals，which select only part of all the candidatesignals.Simulation shows that the modi PTS scheme can not only reduce computational complexity,but PAPRreduction performance is close to that of PTS.
