Technical engineering whitepaper analyzing 3D Urban Ray-Tracing Models for Multi-Path Calibration in Smart Infrastructure RSUs within next-generation 6G cellular and radar architectures.
This paper formalizes 3D Urban Ray-Tracing Models for Multi-Path Calibration in Smart Infrastructure RSUs by establishing the multi-antenna RF channel matrix, noise covariances, and Cramer-Rao lower bounds for joint communication and radar estimation.
Extensive numerical simulations demonstrate that ISACInfra satisfies sub-millisecond detection thresholds while preserving full data throughput across wideband sub-THz carriers.
