Abstract

A novel coding scheme termed redundant bit position rotation sub-block-coding (RBPR SBC) is proposed to reduce the peak-to-average power ratio (PAPR) of OFDM signals. Simulation results show that by using this new scheme, a better performance compared with the standard sub-block-coding (SSBC) can be achieved. According to the probability distribution characteristics of the peak envelope power (PEP) of OFDM signals, a threshold control scheme is proposed to reduce the complexity of this novel coding scheme
