Low Complexity Peak-to-Average Power Ratio Reduction in OFDM-IM
2018 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom), 2018 Orthogonal frequency division multiplexing with index modulation (OFDM-IM) employs the indices of the active subcarriers for information transmission, as an alternative to conventional OFDM. It offers high spectral efficiency and high energy efficiency in comparison to OFDM thanks to the information bits conveyed by IM.

Reducing the Peak to Average Power Ratio of LDS-OFDM signals
2010 7th International Symposium on Wireless Communication Systems, 2010 Low Density Signature-Orthogonal Frequency Division Multiplexing (LDS-OFDM) has been introduced recently as an efficient multiple access technique. High Peak to Average Power Ratio (PAPR) is an important obstacle to multicarrier communication systems. This paper concentrates on the PAPR investigation and its reduction for LDS-OFDM signals. Specifically,
