Abstract
Aiming at the problem that the tradition selective mapping (SLM) algorithm needs transmit side information,a new algorithm-reserved subcarriers-SLM algorithm was proposed,which used the technology of grouping for the subcarriers of orthogonal frequency division multiplexing (OFDM) signals.Meanwhile,it inserted side information into the location of reserved subcarriers after shifting the groups by rows,then select the lowest PAPR groups to send.The simulation results showed that the proposed algorithm didn' t need transmit side information,at same time the peak-to-average power ratio(PAPR) and complexity of the system could be effectively reduced,the bandwidth utilization was improved.
