Punctured DFT codes can be used to implement rate-adaptive source coding, however they perform poorly after even moderate puncturing since the performance of the subspace error localization degrades severely. The proposed subspace-based error localization extends and improves the existing one, based on additional syndrome, and is naturally suitable for rate-adaptive distributed source coding architecture.","authors_text":"Fabrice Labeau, Mojtaba Vaezi","cross_cats":["math.IT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2013-06-27T22:16:27Z","title":"Extended Subspace Error Localization for Rate-Adaptive Distributed Source Coding"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1306.6671","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:6a3900779ebe724727fb33d2a3c6102fd692d2812e2ae37a63c3f90787e837ad","target":"record","created_at":"2026-05-18T03:19:43Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"370cdab779a1cdb90c0d0356a373d03966c8506d4e1492bc5a102ed8142570a1","cross_cats_sorted":["math.IT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2013-06-27T22:16:27Z","title_canon_sha256":"154aa03726de9dbd1dad06e7ab16e1f7762ded8eb9428cdcbcc673291ed1ee3d"},"schema_version":"1.0","source":{"id":"1306.6671","kind":"arxiv","version":1}},"canonical_sha256":"73aab34ddb703c99b39ea52465c6d4695c29f85a542cee4daeede0fa621e1d78","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"73aab34ddb703c99b39ea52465c6d4695c29f85a542cee4daeede0fa621e1d78","first_computed_at":"2026-05-18T03:19:43.433636Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:19:43.433636Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"wOLily/AfT6cDPLtEtmfoLEtCcn9bQEdSy5XAXYpK1uP+DUDZvwWWTSISN4zXfo1amgi2SOPTxFLyf38DX+tBg==","signature_status":"signed_v1","signed_at":"2026-05-18T03:19:43.434270Z","signed_message":"canonical_sha256_bytes"},"source_id":"1306.6671","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6a3900779ebe724727fb33d2a3c6102fd692d2812e2ae37a63c3f90787e837ad","sha256:18bc5abcf48a1596a5f39d7216331d282f9bf8d046bc5775d9cea6d558206b71"],"state_sha256":"552b678645cd097251b1e55c08eb1b1d3e32f37e38a87cd2cfe8e9a48d9723e0"}
