Focusing on the multiple antenna case, we consider a linear antenna array with multiple fixed antenna elements that moves along a line. We assume a full, spatially coherent correlation model and continuous positioning of the array. We provide asymptotically exact approximations to the upper tail of the cumulative distribution function (cdf) of the signal-to-noise ratio (SNR), considering both correlated and uncorrelated antenna elements in the array. We also obtain a novel closed-form expression for"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"Numerical results show that the proposed MA array outperforms single fluid antenna and fixed array systems, with reduced inter-element spacing providing further performance gains.","source":"verdict.strongest_claim","status":"machine_extracted","claim_id":"C1","attestation":"unclaimed"},{"kind":"weakest_assumption","text":"The analysis assumes a full, spatially coherent correlation model together with continuous positioning of the array along a line.","source":"verdict.weakest_assumption","status":"machine_extracted","claim_id":"C2","attestation":"unclaimed"},{"kind":"one_line_summary","text":"Derives SNR CDF tail approximations and closed-form LCR for linear movable antenna arrays with full spatial correlation, showing gains over fixed and fluid antenna systems.","source":"verdict.one_line_summary","status":"machine_extracted","claim_id":"C3","attestation":"unclaimed"},{"kind":"headline","text":"Continuous movable antenna arrays outperform fixed and single fluid antenna systems by improving SNR tail behavior and level crossing rates.","source":"verdict.pith_extraction.headline","status":"machine_extracted","claim_id":"C4","attestation":"unclaimed"}],"snapshot_sha256":"4fc0580732f940c637586a54f2f1caa8281cdbcefddeca24d6d0b2f62d1defdc"},"source":{"id":"2605.16907","kind":"arxiv","version":1},"verdict":{"id":"499ba351-6a67-4db7-b527-7893319352fe","model_set":{"reader":"grok-4.3"},"created_at":"2026-05-19T20:05:29.213150Z","strongest_claim":"Numerical results show that the proposed MA array outperforms single fluid antenna and fixed array systems, with reduced inter-element spacing providing further performance gains.","one_line_summary":"Derives SNR CDF tail approximations and closed-form LCR for linear movable antenna arrays with full spatial correlation, showing gains over fixed and fluid antenna systems.","pipeline_version":"pith-pipeline@v0.9.0","weakest_assumption":"The analysis assumes a full, spatially coherent correlation model together with continuous positioning of the array along a line.","pith_extraction_headline":"Continuous movable antenna arrays outperform fixed and single fluid antenna systems by improving SNR tail behavior and level crossing rates."},"integrity":{"clean":true,"summary":{"advisory":0,"critical":0,"by_detector":{},"informational":0},"endpoint":"/pith/2605.16907/integrity.json","findings":[],"available":true,"detectors_run":[{"name":"cited_work_retraction","ran_at":"2026-05-19T20:52:04.021161Z","status":"completed","version":"1.0.0","findings_count":0},{"name":"doi_title_agreement","ran_at":"2026-05-19T20:31:19.102470Z","status":"completed","version":"1.0.0","findings_count":0},{"name":"doi_compliance","ran_at":"2026-05-19T20:10:48.056780Z","status":"completed","version":"1.0.0","findings_count":0},{"name":"claim_evidence","ran_at":"2026-05-19T18:41:56.272128Z","status":"completed","version":"1.0.0","findings_count":0},{"name":"ai_meta_artifact","ran_at":"2026-05-19T18:33:26.351745Z","status":"skipped","version":"1.0.0","findings_count":0}],"snapshot_sha256":"8756d4f4d8296814a7c18461bb12c8eac7a17f9f7c789ee9bb35cb3134223ae9"},"references":{"count":14,"sample":[{"doi":"","year":2025,"title":"A tutorial on fluid antenna system for 6G networks: Encompassing communication theory, optimization methods and hardware designs,","work_id":"9b7be95a-0c48-4060-9b44-fcd35fb94152","ref_index":1,"cited_arxiv_id":"","is_internal_anchor":false},{"doi":"","year":1950,"title":"K.-K.
