In this paper, a Space-Time Block Coding (STBC) with Dual-Mode Index Modulation Aided OFDM (DM-OFDM-IM) scheme is proposed, which combines the techniques of orthogonal STBC with Alamouti's core and modulation of all OFDM subcarriers within each subblock by pairs of distinguishable constellation sets. The simulation results show that a new signal-code construction STBC-DM-OFDM-IM substantially enha...Show More
