Reliable Near-Field Multi-User Positioning Informed by Two-Stage MUSIC
Jiaying Li, Haifeng Wen, Changsheng You +2
Near-field localization is a promising technique for high-resolution multi-user positioning in future wireless systems, but its performance is often degraded by scattering-induced…
User Localization and Channel Estimation for Pinching-Antenna Systems (PASS)
Xiaoxia Xu, Xidong Mu, Yuanwei Liu +2
This letter proposes a novel user localization and channel estimation framework for pinching-antenna systems (PASS), where pinching antennas are grouped into subarrays on each wave…
Unsupervised Learning for AoD Estimation in MISO Downlink LoS Transmissions
Jiaying Li, Yuanwei Liu, Hong Xing
With the emergence of simultaneous localization and communication (SLAC), it becomes more and more attractive to perform angle of departure (AoD) estimation at the receiving Intern…
Generative Artificial Intelligence (GAI) for Mobile Communications: A Diffusion Model Perspective
Xiaoxia Xu, Xidong Mu, Yuanwei Liu +3
This article targets at unlocking the potentials of a class of prominent generative artificial intelligence (GAI) method, namely diffusion model (DM), for mobile communications. Fi…
Accelerating Mobile Edge Generation (MEG) by Constrained Learning
Xiaoxia Xu, Yuanwei Liu, Xidong Mu +2
A novel accelerated mobile edge generation (MEG) framework is proposed for generating high-resolution images on mobile devices. Exploiting a large-scale latent diffusion model (LDM…
