The selected mapping (SLM) is an effective technique for peak-to-average power reduction (PAPR) of orthogonal frequency division multiplexing (OFDM) signals. SLM has high computational complexity due to the computation of multiple IFFTs. In this paper, low complexity SLM is proposed based on a novel simplified IDFT algorithm developed such that it does not involve any complex arithmetic. The proposed SLM, with U candidate signals, achieves a computational complexity reduction ratio of (1−1
