Multi-domain index modulation for vehicular communications: A survey

Multi-domain index modulation for vehicular communications: A survey
Multi-domain index modulation for vehicular communications: A survey
Vehicular communications have recently attracted considerable attention due to a range of new applications and value-added features. Compared to conventional communication systems, vehicular communications suffer from more grave challenges due to the high-Doppler spread caused by the mobility
of vehicles. In this context, index modulation (IM) constitutes a promising design alterative for vehicular communications due to its appealing benefits. A key feature of IM is that it conveys the information bits by using the specific indices of the transmit resources, such as antenna indices, subcarrier indices, precoder indices and channel-path indices. The resultant transmit signals tend to be sparse in one or several of the resource domains, which increases their robustness and reduces the detection complexity. In this article, we introduce
the basic IM concept and highlight the applications of IM in the context of road vehicle-to-infrastructure (V2I), vehicle-to-vehicle (V2V), conventional railway and high-speed train communication systems. Finally, some design challenges of IM-based vehicular communications are listed for future studies.

Abstract

Vehicular communications have recently attracted considerable attention due to a range of new applications and value-added features. Compared to conventional communication systems, vehicular communications suffer from more grave challenges due to the high-Doppler spread caused by the mobility
of vehicles. In this context, index modulation (IM) constitutes a promising design alterative for vehicular communications due to its appealing benefits. A key feature of IM is that it conveys the information bits by using the specific indices of the transmit resources, such as antenna indices, subcarrier indices, precoder indices and channel-path indices. The resultant transmit signals tend to be sparse in one or several of the resource domains, which increases their robustness and reduces the detection complexity. In this article, we introduce
the basic IM concept and highlight the applications of IM in the context of road vehicle-to-infrastructure (V2I), vehicle-to-vehicle (V2V), conventional railway and high-speed train communication systems. Finally, some design challenges of IM-based vehicular communications are listed for future studies.
