For these sources, we derive the best achievable performance in the rate-distortion sense of any distributed compressed sensing scheme, under the constraint of high--rate quantization. Moreover, under this model we derive a closed--form expression of the rate gain achieved by taking into account the correlation of the sources at the receiver and a closed--form expression of the average performance of the oracle receiver for independent and joint reconstruction. Finally, we show experimentally that the exploitati","authors_text":"Aline Roumy, Enrico Magli, Giulio Coluccia","cross_cats":["math.IT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2014-04-04T12:45:13Z","title":"Operational Rate-Distortion Performance of Single-source and Distributed Compressed Sensing"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1404.1237","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:d15b39732874f09351ecdfd7f35433772df61ae59194d9dfddb3f33b5bed785a","target":"record","created_at":"2026-05-18T02:54:31Z","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":"f9ac5560e6514ecf508573dcdffd5d6ffd3d86f288686824e2430ee0bdba9b7a","cross_cats_sorted":["math.IT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2014-04-04T12:45:13Z","title_canon_sha256":"fd9ebe4216eb9d928a52296c3696ee3f0799ae8cc73654418952146cfb05c470"},"schema_version":"1.0","source":{"id":"1404.1237","kind":"arxiv","version":1}},"canonical_sha256":"d7c863cc6dc73f602cb0683d8a4b67ad65d8fb9f28284486af1cf06e5cc62cff","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d7c863cc6dc73f602cb0683d8a4b67ad65d8fb9f28284486af1cf06e5cc62cff","first_computed_at":"2026-05-18T02:54:31.994661Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:54:31.994661Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"4dvW/ps1OgHsncu2x5GGEtXqJjnJmdzyhrMIuvqjqScE3vhGxnBLcTdl4Aq1XNyZTVQrIaj5Uio9Edr+jb6CDw==","signature_status":"signed_v1","signed_at":"2026-05-18T02:54:31.995067Z","signed_message":"canonical_sha256_bytes"},"source_id":"1404.1237","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d15b39732874f09351ecdfd7f35433772df61ae59194d9dfddb3f33b5bed785a","sha256:f4c07fa8ff1662ffdc76c7870ca3e83a710ceef6ad5ad114ea3285fa7ed5bd8d"],"state_sha256":"1864471106239ddac5f56f6e01735a802fc9df8ac698914efa64e98efad74db7"}
