Orthogonal time frequency space (OTFS) modulation is strongly considered as a promising
solution for high-mobility communications. In contrast to conventional modulation …

The internet of things (IoT) has been widely considered to be integrated with high-speed
railways to improve safety and service. It is important to achieve reliable communication in …

Recently, orthogonal time frequency space (OTFS) was presented to alleviate severe
Doppler effects in high mobility scenarios. Most of the current OTFS detection schemes rely …

A spatial modulation-aided orthogonal time frequency space (SM-OTFS) scheme is
proposed for high-Doppler scenarios, which relies on a low-complexity distance-based …

In this paper, a spatial-index modulation (SIM) based orthogonal time frequency space
(OTFS) system, named SIM-OTFS, is proposed to enhance the effectiveness and the …

In LEO (Low Earth Orbit) satellite communication system, the orbit height of the satellite is
low, the transmission delay is short, the path loss is small, and the frequency multiplexing is …

In this paper, we take the spatial and delay-Doppler dimensions into account and propose a
novel transmission scheme combining quadrature spatial modulation (QSM) and orthogonal …

This paper investigates the security performance of a cooperative multicast-unicast system,
where the users present the feature of high mobility. Specifically, we develop the non …

In this paper, we propose a spatial modulation (SM) space time block code (STBC) aided
orthogonal time frequency space modulation (SM-STBC-OTFS) system to achieve both high …

In this paper, spatial multiplexing aided orthogonal time-frequency space with index
modulation (OTFS-IM) is conceived, which combines the benefits of both OTFS-IM and …
