While the fifth-generation systems are being rolled out across the globe, researchers have
turned their attention to the exploration of radical next-generation solutions. At this early …

The Internet of Things (IoT) is envisioned to connect everything, spanning from terrestrial to
nonterrestrial terminals, where reliable communication is expected to be allowed in both …

Sixth-generation (6G) wireless networks are envisioned to provide global coverage for the
intelligent digital society of the near future, ranging from traditional terrestrial to non-terrestri …

We consider a joint radar parameter estimation and communication system using orthogonal
time frequency space (OTFS) modulation. The scenario is motivated by vehicular …

Orthogonal Frequency Division Multiplexing (OFDM) has been the waveform of choice for
most wireless communications systems in the past 25 years. This book addresses the “what …

This paper proposes an off-grid channel estimation scheme for orthogonal time-frequency
space (OTFS) systems adopting the sparse Bayesian learning (SBL) framework. To avoid …

Orthogonal Time Frequency Space (OTFS) modulation has been recently proposed to be
robust to channel induced Doppler shift in high mobility wireless communication systems …

In this paper, we investigate the impacts of transmitter and receiver windows on the
performance of orthogonal time-frequency space (OTFS) modulation and propose window …

In the 6G era, Space-Air-Ground Integrated Network (SAGIN) are anticipated to deliver
global coverage, necessitating support for a diverse array of emerging applications in high …

Although it is often used in the orthogonal frequency division multiplexing (OFDM) systems,
application of massive multiple-input multiple-output (MIMO) over the orthogonal time …
