AFDM-ISAC With Fractional Delay-Doppler Coupling
Shaohua Li, Cunhua Pan, Hong Ren +2
Affine frequency division multiplexing (AFDM) is a promising chirp-based multicarrier waveform for high-mobility integrated sensing and communication (ISAC). Accurate angle, delay,…
Subspace Fusion Sensing for Cooperative ISAC
Yining Xu, Cunhua Pan, Jun Tang +2
This paper proposes a subspace fusion sensing algorithm for cooperative integrated sensing and communication. First, we stack the received signals from access points (APs) into a t…
A Measurement-Based Parameterization of Physics Reflection Models for Terahertz Communication
Taihao Zhang, Chenzhou Lin, Cunhua Pan +6
The accurate modeling of reflection coefficients is pivotal for developing reliable channel models in emerging terahertz (THz) communications. This study establishes a 300400…
Coverage Analysis of Rydberg Atom Quantum Receiver Arrays: A Stochastic Geometry Approach
Dongnan Xia, Cunhua Pan, Hong Ren +3
Rydberg atomic quantum receivers (RAQRs) offer quantum-limited sensitivity and broadband tunability. It is not obvious whether this device-level advantage also improves network rel…
CAT-MoEformer: Context-Aware Temporal MoE Transformer for Beam Prediction
Changkai Zhou, Cunhua Pan, Hong Ren +1
This paper proposes CAT-MoEformer, a context-aware transformer with scene-conditioned mixture-of-experts (MoE) feed-forward networks, for proactive mmWave beam prediction from comp…
Channel Estimation for Beyond Diagonal RIS-Aided Multi-User mmWave Systems
Linyu Peng, Tian Qiu, Cunhua Pan +3
Beyond diagonal reconfigurable intelligent surface (BD-RIS) represents a promising architecture for advancing millimeter-wave (mmWave) communications. However, its intricate inter-…
