OFDM-IM, which uses the indices of active subcarriers to carry additional information bits, is a novel multi-carrier transmission technique. In this letter, by exploiting the special design of OFDM-IM, we propose an analytical approach to evaluate the error probability of OFDM-IM subject to carrier frequency offset (CFO) in fading channels, where the inter-carrier interference (ICI) is properly divided...
Interleaved subcarrier-index modulation for orthogonal frequency division multiplexing (ISIM-OFDM) is a recently developed technique, where the indices of OFDM subcarriers are utilized to convey information bits and subcarrier-level interleaving scheme is considered. For the conventional OFDM system, the main drawbacks lie in the high peak-to-average power ratio (PAPR) at transmitter and its sensitiveness...
Orthogonal frequency division multiplexing (OFDM) has attracted much attention as it is convenient to implement and robust to multiple path fading. However, the system performance of OFDM will be degraded seriously in high-speed wireless communications, since it is much sensitive to severe inter-carrier interference (ICI) caused by high-speed vehicles. Recently, a novel modified OFDM system, called...
