Abstract

This study found that, compared to the modified Hadamard sequence, the SLM-OFDM device with the improved chaotic sequence can lower PAPR by at least 0.4 dB. Furthermore, we found that the SLM-OFDM system outperforms the comparable PTS-OFDM system in terms of PAPR performance when using modified chaotic sequences. The PAPR reduction capabilities of the PTS-OFDM scheme with 4- to 8-QAM order translations and MPSM were pretty close with the same number of possible sequences. The proposed 4-ary to 8-QAM and 4-ary to 8-PSK mapping algorithms beat the existing MPSM in terms of BER performance. This is because M-2M translation only uses two stage coefficients for SLM and PTS-OFDM circuits, increasing the cluster size by one.
