Selected mapping (SLM) is one of the most widely used peak-to-average power ratio (PAPR) reduction schemes-it selects and transmits a signal having the smallest PAPR among candidate signals by performing a full search (FS). In this Letter, a simple modification to reduce the computational complexity of SLM-based PAPR schemes is proposed that terminates searching process when it meets a candidate signal not causing a clipping, instead of having the smallest PAPR.
