Different from the traditional MM-FDR protocol, a general model where sources/destinations are allowed to equip with multiple antennas is considered. In contrast to the conventional MIMO system, massive MIMO must be built with low-cost components which are prone to hardware impairments. In this paper, the effect of hardware impairments is taken into consideration, and is modeled","authors_text":"Dongmei Zhang, Kui Xu, Wenfeng Ma, Xiaochen Xia, Youyun Xu","cross_cats":["math.IT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2015-09-18T12:02:38Z","title":"Hardware Impairments Aware Transceiver for Full-Duplex Massive MIMO Relaying"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1509.05600","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":"sha256:683b95e000ab85a62fe3f1292c24ca387168736586716f5718b0834c00d719d5","target":"record","created_at":"2026-05-18T01:22:20Z","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":"9e5b71ccc642cd8492d5d97b5aef779cccccdbf2b0b6bee2e073ae45372c38f6","cross_cats_sorted":["math.IT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2015-09-18T12:02:38Z","title_canon_sha256":"23a05a81544915cb70cdd1b0017eae01bb9a5f8242e1ba7fc31be83bc12c1c3c"},"schema_version":"1.0","source":{"id":"1509.05600","kind":"arxiv","version":1}},"canonical_sha256":"919232da3395a06a3c26f92b638d6450e74c30566dca8042d3e52102417556f1","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"919232da3395a06a3c26f92b638d6450e74c30566dca8042d3e52102417556f1","first_computed_at":"2026-05-18T01:22:20.137419Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:22:20.137419Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"YN1WyjNzo3cdVuoR1I8k77tnPjl/KOcmRn+sJLj6POK+/psjTuguWuvG8b1/eA7p8W9wQ9tDtxalg9XmQ+LyAg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:22:20.138140Z","signed_message":"canonical_sha256_bytes"},"source_id":"1509.05600","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:683b95e000ab85a62fe3f1292c24ca387168736586716f5718b0834c00d719d5","sha256:a5f50ed84563770d39f224c4cbe9dc6e53b65c3ab443106eb9354d69e17e3424"],"state_sha256":"c98491f5014c330b3c2bc6585678c94cc739dc94edd60380f067423c65b238e5"}
