Abstract
This letter deals with a peak-To-Average power ratio (PAPR) reduction scheme for orthogonal frequency division multiplexing (OFDM) systems with signal space diversity. An original algorithm for the selection of two rotated and cyclically Q-delayed (RCQD) QAM constellations is proposed to jointly optimize the bit error rate (BER) and the blind detection performance of a selected mapping (SLM) technique. Simulation results show that the proposed method achieves a large PAPR reduction with no spectral spoilage and also enhances the BER performance in the case of DVB-T2 over different channels.
