The proposed structure utilizes reference receiver chains to obtain reference signals for digital self-interference cancellation, which means that all the transmitter-induced nonidealities will be included in the digital cancellation signal. To the best of our knowledge, this type of a structure has not been discussed before in the context of full-duplex transceivers. First, we will analyze the overall achievable performance of the proposed cancellation scheme, while","authors_text":"Dani Korpi, Lauri Anttila, Mikko Valkama","cross_cats":["math.IT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2014-05-09T10:44:11Z","title":"Reference Receiver Based Digital Self-Interference Cancellation in MIMO Full-Duplex Transceivers"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1405.2202","kind":"arxiv","version":2},"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:d6fa2b6dec74692aaa08a0b01b326d6c966cd82f77977f9b5e6f363886e52b2c","target":"record","created_at":"2026-05-18T00:58:41Z","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":"b1d44ea5e916064b6ce76ec29f9dd4d2b46c112e222b9796bda3c7564468650b","cross_cats_sorted":["math.IT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2014-05-09T10:44:11Z","title_canon_sha256":"357707b5a74bf0870098d5627839fec567287f5aa933d767f428de7bf24c2a08"},"schema_version":"1.0","source":{"id":"1405.2202","kind":"arxiv","version":2}},"canonical_sha256":"d08dbdf17c3b6f8d943e41b309cc1c2982858bd7d381154032bf2514823c76cc","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d08dbdf17c3b6f8d943e41b309cc1c2982858bd7d381154032bf2514823c76cc","first_computed_at":"2026-05-18T00:58:41.477778Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:58:41.477778Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"YR8jEOutn0XumOiO1PAF7e5qUDgkz3PftO0iEVgh1ZjK5KDZeI1aR0h4kRAFnK/rVIIeLKBd5jfQze5kYVfuAg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:58:41.478389Z","signed_message":"canonical_sha256_bytes"},"source_id":"1405.2202","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d6fa2b6dec74692aaa08a0b01b326d6c966cd82f77977f9b5e6f363886e52b2c","sha256:e15d44e5ce71e9547bd2063a32e01b7d91a1bfb690a54bf6021345e9bacdd10c"],"state_sha256":"2e4d482e20ea58f189c6194a49b164228da1407b2041b4184d30ca5fa7a88091"}
