Abstract

Unmanned Aerial Vehicles (UAVs) are envisioned to be an important part of the device-centric Internet-of-Things (IoT). These bespoke Unmanned Aircraft Systems (UASs) that support UAVs significantly differ from traditional terrestrial and aeronautical networks, both of which are evolving towards their next-generation forms. The major challenges of the UAS include (1) the augmented interference due to strong Line-of-Sight (LoS) (2) the dynamic shadowing effects owing to 3-D aerial maneuvering, (3) the excessive Doppler shift owing to high UAV mobility as well as (4) the Size, Weight, And Power (SWAP) constraints. Against this background, we propose to invoke the recently developed coherent/non-coherent Spatial Modulation (SM) and its diversity-oriented counterpart of Space-Time Block Coding using Index Shift Keying (STBC-ISK). These arrangements employ multiple Transmit Antennas (TAs) in order to improve the network's Quality-of-Service (QoS), but they only use a single RF chain. Furthermore, based on the throughput, delay and power-efficiency, we conceive a novel three-fold adaptivity design, where the UAS may adaptively (I) switch between coherent and non-coherent schemes, (II) switch between single- and multiple-TA based arrangements as well as (III) switch between high-diversity and high-spectral-efficiency multiple-TA based schemes.
