(S) under bare (l) under bar ected (m) under bar apping (SLM) peak-power reduction [1] is distortionless as it selects the actual transmit signal from a set of alternative signals, which all represent the same information. The specific signal generation information needs to be transmitted and carefully protected against bit errors, Here, we propose an extension of SLM, which employs scrambling and refrains from the use of explicit side information in the receiver Some additional complexity and nearly vanishing redundancy is introduced to achieve markedly improved transmit signal statistics. Even though SLM is applicable with any modulation, we concentrate on orthogonal frequency-division multiplexing (OFDM) in this letter.
