Transmitting Data Through Reconfigurable Intelligent Surface: A Spatial Sigma-Delta Modulation Approach
Wai-Yiu Keung, Hei Victor Cheng, Wing-Kin Ma
Transmitting data using the phases on reconfigurable intelligent surfaces (RIS) is a promising solution for future energy-efficient communication systems. Recent work showed that a…
Realistic Speech-to-Face Generation with Speech-Conditioned Latent Diffusion Model with Face Prior
Jinting Wang, Li Liu, Jun Wang +1
Speech-to-face generation is an intriguing area of research that focuses on generating realistic facial images based on a speaker's audio speech. However, state-of-the-art methods…
NOMA Versus Massive MIMO in Rayleigh Fading
Kamil Senel, Hei Victor Cheng, Emil Björnson +1
This paper compares the sum rates and rate regions achieved by power-domain NOMA (non-orthogonal multiple access) and standard massive MIMO (multiple-input multiple-output) techniq…
A Lattice-Theoretic Characterization of Optimal Minimum-Distance Linear Precoders
D. Kapetanovic, H. V. Cheng, W. H. Mow +1
This work investigates linear precoding over non-singular linear channels with additive white Gaussian noise, with lattice-type inputs. The aim is to maximize the minimum distance…
