PAPR Reduction for OFDM/OQAM Signals Using Offset-Symbols Joint SLM Method

Abstract

—A novel offset-symbols joint selective mapping (JSLM) scheme is proposed for the peak-to-average power ratio (PAPR) reduction in the Orthogonal Frequency Division Multiplexing with Offset Quadrature Amplitude Modulation (OFDM/OQAM) system. By exploiting the dispersive energy of the prototype filter, the proposed J-SLM scheme multiplies the real and imaginary parts of each data block with different phase rotation factors, and then adopts a sequential optimization procedure to jointly optimize the real and imaginary parts for each data block. Simulation results show that the J-SLM scheme could offer much better PAPR reduction and Bit Error Rate (BER) performances than the available SLM-based schemes of OFDM/OQAM signals.
