摘要： A method based on orthogonal frequency division multiplexing (OFDM) called OFDM-subcarrier gap and index modulation (OFDM-SGIM) is proposed in which the gaps between the active subcarriers are exploited to transmit extra bits alongside the conventional QAM symbols. Thereafter, the index modulation is combined with the new proposed OFDM-based scheme to guarantee a fixed subblock size.
