The proposed approach, called Non-Surjective Finite Alphabet Iterative Decoders (NS-FAIDs), exploits the robustness of message-passing LDPC decoders to inaccuracies in the calculation of exchanged messages, and it is shown to provide a unified framework for several designs previously proposed in the literature. NS-FAIDs are optimized by density evolution for regular and irregular LDPC codes, and are shown to provide different trade-offs between hardware complex","authors_text":"David Declercq, Fakhreddine Ghaffari, Khoa Le, Oana Boncalo, Thien Truong Nguyen-Ly, Valentin Savin","cross_cats":["cs.AR"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.SP","submitted_at":"2017-08-23T09:42:17Z","title":"Analysis and Design of Cost-Effective, High-Throughput LDPC Decoders"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1709.10396","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:dd50762f7ee0e2f6b5f4113c6e9919ac55083c8aa6522481ba9377ef45650f7a","target":"record","created_at":"2026-05-18T00:34:01Z","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":"440f4a586bfe3833477ea5288d760770f0e18a8be9547001d6de1fe120e2f625","cross_cats_sorted":["cs.AR"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.SP","submitted_at":"2017-08-23T09:42:17Z","title_canon_sha256":"9c91bc56eafebd8d6f7eaa0d9c11a1ff5ee5a780b43f5b15065321f568dff1e7"},"schema_version":"1.0","source":{"id":"1709.10396","kind":"arxiv","version":1}},"canonical_sha256":"6ec185bbe244d1911f107943e754e3fcfadd99afed1ddf3921a738a0bb7a5dc9","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"6ec185bbe244d1911f107943e754e3fcfadd99afed1ddf3921a738a0bb7a5dc9","first_computed_at":"2026-05-18T00:34:01.207326Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:34:01.207326Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"mh2kQcrras+RmS/UN7qgrWt3w/muIgGJYuBKFBwJJJqjutFhPAU+9ULV7VYAgMOuY38khEzBpYRg6WKgyLHQDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:34:01.208069Z","signed_message":"canonical_sha256_bytes"},"source_id":"1709.10396","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:dd50762f7ee0e2f6b5f4113c6e9919ac55083c8aa6522481ba9377ef45650f7a","sha256:8165f6621b74576d61ee91b61d2e4e68b365a697c138f9e6935ba950a877c70a"],"state_sha256":"1178b753b3ff0aeff175c70bffb57c1198cc8b05c0e22320592a37cf0d7868b8"}
