Enhancing Diversity of OFDM with Joint Spread Spectrum and Subcarrier Index Modulations
Vu-Duc Ngo, Thien Van Luong, Nguyen Cong Luong +4
This paper proposes a novel spread spectrum and sub-carrier index modulation (SS-SIM) scheme, which is integrated to orthogonal frequency division multiplexing (OFDM) framework to…
