Design Criteria for Phase Sequences in Selected Mapping

We propose design criteria for phase sequences in Selected Mapping (SLM): the average and variance of peak-to-average power ratio (PAPR) of the phase sequences themselves. We evaluate the effects of SLM with some phase sequences for reducing the PAPR of multicarrier code division multiple access (MC-CDMA). We show that our design criteria are effective for designing phase sequences in SLM. We also show that SLM is more effective than partial transmit sequences (PTS) for reducing the PAPR of MC-CDMA at the same amount of side information.
