One promising solution to address this challenge is to adopt the low-resolution analog-to-digital converter (ADC) architecture. However, the practical implementation of such architecture is challenging due to the required complex signal processing to compensate the coarse quantization caused by low-resolution ADCs. Therefore, few high-resolution ADCs are reserved in the recently proposed mixe","authors_text":"Jiayi Zhang, Linglong Dai, Shi Jin, Xu Li, Ziyan He","cross_cats":["math.IT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2017-03-10T12:01:08Z","title":"Performance Analysis of Mixed-ADC Massive MIMO Systems over Rician Fading Channels"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1703.03642","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":"sha256:56da7ba0eaa39246887c434a6c730cd705a9ac3bd811a813114c097c2a28de78","target":"record","created_at":"2026-05-18T00:48:58Z","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":"249ce90566c0493f75104a3f333f6111016c0c5caeb92bd78de407bc52d70afe","cross_cats_sorted":["math.IT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2017-03-10T12:01:08Z","title_canon_sha256":"0365a064eb15e2872bb95223dd3ca0649d9bf36eb76a786ee61c457c79874d98"},"schema_version":"1.0","source":{"id":"1703.03642","kind":"arxiv","version":1}},"canonical_sha256":"e4334fcb21557ffc39e7a99ce0b041ead9886c091d5920007f28b7351b3b0559","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e4334fcb21557ffc39e7a99ce0b041ead9886c091d5920007f28b7351b3b0559","first_computed_at":"2026-05-18T00:48:58.446621Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:48:58.446621Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"nt/C1XgaqnCKyljVhjMn5NX9+d5X7CjtrU+b5dVSHu9LJZcnCIa8hI2MGMW3Sx2SEUxpCBuJS8lat/SeYvlmDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:48:58.447275Z","signed_message":"canonical_sha256_bytes"},"source_id":"1703.03642","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:56da7ba0eaa39246887c434a6c730cd705a9ac3bd811a813114c097c2a28de78","sha256:a0dfc54ded32f49f300f7e7d9de60d44e0b8a3659486ef4eb37ea992b7aaeccf"],"state_sha256":"c26df130f6a81f4a4544400c1c530309935509288abfebc4df4aebe0a2023573"}
