Abstract :
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 to inter-carrier interference (ICI) in a highly mobile environment. In this paper, the performance evaluation in PAPR and ICI for ISIM-OFDM system is presented. Simulation results show that ISIM-OFDM system can efficiently reduce the PAPR and is more robust to ICI compared with traditional OFDM system.
