A blind selected mapping technique for low-PAPR single-carrier signal transmission

Single-carrier (SC) signals have a low peak-to-average power ratio (PAPR) property. However, the PAPR becomes higher as the modulation level increases. We have recently proposed a frequency-domain selected mapping (FD-SLM) which can effectively reduce PAPR of SC signal with high modulation level, but standard SLM technique requires the transmission of side-information to the receiver side. In this paper, a new FD-SLM with minimum mean-square error (MMSE) based blind signal detection is proposed, where there is no change on SLM algorithm at the transmitter and no necessity of side-information transmission. Simulation results show that the proposed blind FD-SLM technique reduces the PAPR of SC signals without significant degradation of bit-error rate (BER) performance.
