Cognitive Link-Flexible FTN-OTFS Design for High-Mobility LEO Satellite Communications
Chaorong Zhang, Benjamin K. Ng, Hui Xu +4
Low Earth orbit (LEO) satellite links are challenged by pronounced signal-to-noise ratio (SNR) variation and severe Doppler shifts. Although mobility robustness is provided by orth…
On the Impact of Phase Errors in Phase-Dependent Amplitudes of Near-Field RISs
Ke Wang, Chan-Tong Lam, Benjamin K. Ng +1
This paper investigates mutual coupling between phase-dependent amplitudes (PDAs) and designed phase shifts within pixels of near-field (NF) reconfigurable intelligent surfaces (RI…
From Reliability to Security: How RIS-Assisted Adaptive SM and SSK Enhances Wireless Systems
Chaorong Zhang, Benjamin K. Ng, Ke Wang +2
This paper proposes two novel wireless transmission schemes, namely reconfigurable intelligent surface (RIS)-assisted received adaptive spatial modulation (RASM) scheme and RIS-ass…
RIS-Assisted Received Adaptive Spatial Modulation for Wireless Communications
Chaorong Zhang, Hui Xu, Benjamin K. Ng +2
A novel wireless transmission scheme, as named the reconfigurable intelligent surface (RIS)-assisted received adaptive spatial modulation (RASM) scheme, is proposed in this paper.…
