Abstract :
High peak-to-average power ratio (PAPR) is one of the major drawbacks of orthogonal frequency division multiplexing (OFDM). In [8] a low-complexity probabilistic scheme to reduce PAPR in OFDM, called erasure pattern selection (EPS), was proposed. The EPS scheme described in [8] requires the transmission of side information with proper coding. In this paper we address waveform design for OFDM transmission and investigate a method that avoids transmission of side information. Simulation results show that the probability of incorrect detection of the selected erasure pattern is smaller than 10-3 for SNR larger than 6 dB. This means that only 1 in 1000 symbols have to be retransmitted. Also, EPS provide a reduction in PAPR of about 1.5 dB.
