Practical limitations may limit their use; thus, cooperative transmissions have been proposed to introduce diversity without the need for multiple antennas. We propose a novel cooperative scheme that ...

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 ...
