Abstract

Selected mapping (SLM) and partial transmit sequence (PTS) are two existing distrotionless crest factor reduction (CFR) schemes that have been proposed for orthogonal frequency division multiplexing (OFDM). Previously, it was argued that SLM and PTS have comparable CFR performance but that the latter has lower computational complexity because it uses fewer IFFTs. In this paper, we show that the overall computational complexity of PTS may be higher than that of SLM, but that SLM always has better CFR performance as quantified through a per unit of complexity metric
