In orthogonal frequency division multiplexing with index modulation (OFDM-IM), the active subcarriers can convey information bits by modulated symbols as well as their indices. OFDM-IM has attracted a great deal of attention from researchers by virtu

This paper aimed to investigate how to construct a phase-generation mechanism with a systematic structure and without diminishing the peak-to-average power ratio (PAPR) reduction performance of a conventional selective mapping (SLM) technique. The SL

One of the most well-known techniques to reduce the problem of PAPR in orthogonal frequency division multiplexing (OFDM) systems is selected mapping (SLM). The chief drawback of this method is transmission of several additional bits, side information

The selected mapping (SLM) is an effective technique for peak-to-average power reduction (PAPR) of orthogonal frequency division multiplexing (OFDM) signals. SLM has high computational complexity due to the computation of multiple IFFTs. In this pape

Orthogonal frequency-division multiplexing (OFDM) is an attractive multicarrier technique for the simplicity of equalization and high data throughput. However, the transmitted OFDM signal has a very high peak-to-average power ratio (PAPR), which seve
