Latency Minimization for Hybrid-Frequency UHD Upload in Double-IRS-Aided HSR Networks
Tianyou Li, Tonghua Wei, Dapeng Li
Real-time mechanical fault diagnosis in high-speed railway (HSR) networks requires ultra-reliable and low-latency upload of ultra-high-definition (UHD) video streams. However, ener…
Fundamental Limits for Near-Field Sensing -- Part II: Wide-Band Systems
Tong Wei, Kumar Vijay Mishra, Bhavani Shankar M. R. +1
Near-field sensing with extremely large-scale antenna arrays (ELAAs) in practical 6G systems is expected to operate over broad bandwidths, where delay, Doppler, and spatial effects…
Fundamental Limits for Near-Field Sensing -- Part I: Narrow-Band Systems
Tong Wei, Kumar Vijay Mishra, Bhavani Shankar M. R. +1
Extremely large-scale antenna arrays (ELAAs) envisioned for 6G enable high-resolution sensing. However, the ELAAs worked in extremely high frequency will push operation into the ne…
An iteration-free approach to excitation harmonization
Patrick Hippold, Gleb Kleyman, Lukas Woiwode +6
Sinusoidal excitation is particularly popular for testing structures in the nonlinear regime. Due to the nonlinear behavior and the inevitable feedback of the structure on the exci…
