Space-Time Block Coded Spatial Modulation

Abstract

Email\ud Print\ud Request Permissions\ud A novel multiple-input multiple-output (MIMO) transmission scheme, called space-time block coded spatial modulation (STBC-SM), is proposed. It combines spatial modulation (SM) and space-time block coding (STBC) to take advantage of the benefits of both while avoiding their drawbacks. In the STBC-SM scheme, the transmitted information symbols are expanded not only to the space and time domains but also to the spatial (antenna) domain which corresponds to the on/off status of the transmit antennas available at the space domain, and therefore both core STBC and antenna indices carry information. A general technique is presented for the design of the STBC-SM scheme for any number of transmit antennas. Besides the high spectral efficiency advantage provided by the antenna domain, the proposed scheme is also optimized by deriving its diversity and coding gains to exploit the diversity advantage of STBC. A low-complexity maximum likelihood (ML) decoder is given for the new scheme which profits from the orthogonality of the core STBC. The performance advantages of the STBC-SM over simple SM and over V-BLAST are shown by simulation results for various spectral efficiencies and are supported by the derivation of a closed form expression for the union bound on the bit error probability

“…Moreover, the single-RF design is capable of employing a low-complexity single-stream maximum-likelihood (ML) detector and offering an increased energy efficiency compared with multiple-RF-chain-based schemes. As a result, SM constitutes a promising transmission candidate for multiple-input-multiple-output (MIMO) design [7][8][9]. It is found that the performances (i.e.…”

“…SM can also be combined with other MIMO technologies such as the space-time coding. Related research works were reported in [21]- [23]. Beside radio frequency wireless communications, SM has also been used in optical wireless communication systems [24], [25].…”

“…STBC-CSM). The proposed STBC-CSM scheme was shown to increase spectral efficiency with the help of the extended code set when compared to the pioneering design in [6], resulting in higher spectral efficiencies even when employing fewer transmit antennas. Moreover, the STBC-CSM scheme has achieved considerable coding gain distances (CGDs) between the available CWs that pave the way for operating at lower bit error rates (BERs) when compared to the H-STBC-SM and CIOD-SM-H schemes and at nearly the same BERs as the STBC-SM.…”
