Selected Mapping with Explicit Transmission of Side Information

The high peak-to-average power ratio (PAR) of the transmit signal is one serious issue, which occurs in orthogonal frequency-division multiplexing (OFDM). Hence, the application of a PAR reduction algorithm, which controls the peak-power of the transmit signal, is indispensable. In this paper, we consider selected mapping (SLM), a very popular technique for PAR reduction and its recently proposed extension successive SLM. One drawback of (successive) SLM is that the transmission of side information is necessary, which is extraordinarily prone to transmission errors. In this paper, the explicit transmission of this side information is considered. In order to reduce the increase in bit error rates, due to an erroneous detection of the side information, its estimation at the receiver and its mapping to signals embedded into the OFDM frame is optimized. In this case the application of successive SLM is very advantageous compared to the original approach of SLM as the detection error rate can be reduced significantly. Moreover, with successive SLM almost no differences between explicit transmission and perfect knowledge of the side information in terms of bit error rates occur.
