About this topic:
6G networks are expected to deliver integrated sensing and communication (ISAC) capabilities mainly in the lower frequency bands, where conventional delay- and angle-based processing suffers from low resolution under limited bandwidth and array sizes. Distributed multiple-input multiple-output (D-MIMO) architectures offer a different resource in this regime since spatially separated, phase-coherent access points (APs) provide high-precision distance information through the carrier phase, so that the entire D-MIMO network acts as a single large, sparsely sampled aperture.
In this talk, the presenter will examine what benefits such phase coherence brings to distributed ISAC (D-ISAC) systems in terms of localization and sensing, and what algorithmic and hardware challenges it introduces in return. He begins with phase-coherent localization of connected devices, moving from wideband localization with multi-antenna APs to phase-only frugal localization with minimal resources, i.e., a single subcarrier at single-antenna APs, and discuss low-complexity algorithms to deal with ambiguities, learning-based AP selection strategies, and deployment optimization methods. He then investigates phase-coherent sensing of passive objects, covering coherent multistatic imaging, spatial-frequency resource allocation to manage ISAC trade-offs, and Doppler-only sensing. These studies show that limited bandwidth and aperture need not be a showstopper in D-ISAC systems provided that ambiguity and synchronization are accounted for.
