Distortionless reduction of peak power without explicit side information

Selected mapping (SLM) peak power reduction is distortionless as it selects the actual transmit signal from a set of alternative signals, which all represent the same information. Usually, the specific signal generation information needs to be transmitted and carefully protected against bit errors....

Description
Summary:Selected mapping (SLM) peak power reduction is distortionless as it selects the actual transmit signal from a set of alternative signals, which all represent the same information. Usually, 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 transmitting explicit side information. 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).
