Under the assumption of unknown channel state information (CSI) at the Rx, two schemes are considered: pilot sensing (PS) and data-aided sensing (DAS). The communication rate-sensing distortion functions for both schemes are characterized. For the DAS scheme, a closed-form asymptotic expression for the sensing distortion is derived by using random","authors_text":"Chengkai Zhao, Dongsheng Peng, Jun Chen, Ping Chen, Yihong Li, Zhiqing Wei","cross_cats":["math.IT"],"headline":"Data-aided sensing in non-coherent ISAC systems delivers a strict 3 dB effective SNR improvement at low SNR and faster distortion scaling at high SNR than pilot sensing.","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2026-05-15T17:11:50Z","title":"Fundamental Performance Limits of Non-Coherent ISAC: A Data-Aided Sensing Perspective"},"references":{"count":28,"internal_anchors":0,"resolved_work":28,"sample":[{"cited_arxiv_id":"","doi":"","is_internal_anchor":false,"ref_index":1,"title":"Integrated sensing and communications: Toward dual-functional wireless networks for 6G and beyond,","work_id":"3fae8072-eada-4944-ab7c-35b24cdfe601","year":2022},{"cited_arxiv_id":"","doi":"","is_internal_anchor":false,"ref_index":2,"title":"A survey on fundamental limits of integrated sensing and communication,","work_id":"f66316ec-8b55-4a99-8ab8-9ead13c3cca3","year":2022},{"cited_arxiv_id":"","doi":"","is_internal_anchor":false,"ref_index":3,"title":"Twelve scientific challenges for 6G: Rethinking the foundations of communications theory,","work_id":"b41e1dff-eb4c-49d6-8bbe-59b13ddc197c","year":2023},{"cited_arxiv_id":"","doi":"","is_internal_anchor":false,"ref_index":4,"title":"A vision of 6G wireless systems: Applications, trends, technologies, and open research problems,","work_id":"42b2c0c1-8cec-437e-afc0-817d94000d12","year":2020},{"cited_arxiv_id":"","doi":"","is_internal_anchor":false,"ref_index":5,"title":"Waveform design and signal processing aspects for fusion of wireless communications and radar sensing,","work_id":"55850a75-d3cc-4b63-9e9c-b41be07cd1d1","year":2011}],"snapshot_sha256":"3ad510b018367e0f8875d59149435705a472124b0722bb61f4d3b4220a1b5116"},"source":{"id":"2605.16196","kind":"arxiv","version":1},"verdict":{"created_at":"2026-05-19T18:37:18.879921Z","id":"d8891783-cd1a-4a17-9cfe-56adce90fe09","model_set":{"reader":"grok-4.3"},"one_line_summary":"In non-coherent bistatic MIMO ISAC, data-aided sensing yields a strict 3 dB effective SNR improvement at low SNR and faster performance scaling at high SNR versus pilot sensing, via closed-form random matrix theory asymptotics.","pipeline_version":"pith-pipeline@v0.9.0","pith_extraction_headline":"Data-aided sensing in non-coherent ISAC systems delivers a strict 3 dB effective SNR improvement at low SNR and faster distortion scaling at high SNR than pilot sensing.","strongest_claim":"For the DAS scheme, a closed-form asymptotic expression for the sensing distortion is derived by using random matrix theory (RMT).
