In this technology, Base Station (BS) is equipped with a large number of antennas. Employing high resolution analog-to-digital converters (ADCs) for all antennas may cause high costs and high power consumption for the BS. By performing numerical results, we evaluate the use of low-resolution ADCs for uplink massive MIMO by analyzing Bit Error Rate (BER) performance for different detection techniques (MMSE, ZF) and different modulations (QPSK, 16-QAM) to find an optim","authors_text":"Azad Azizzadeh, Reza Mohammadkhani, Seyed Vahab Al-Din Makki","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.SP","submitted_at":"2017-10-01T11:38:13Z","title":"BER Performance of Uplink Massive MIMO With Low-Resolution ADCs"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1710.00335","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":"sha256:1b1eaa34df56fddee5d50581043ff01d61d5028449111ce7960118d79901e55e","target":"record","created_at":"2026-05-18T00:33:55Z","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":"73a0273c951d0c2039ad661224a1d33af4b42b87cae68680fa6177620a7b6969","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.SP","submitted_at":"2017-10-01T11:38:13Z","title_canon_sha256":"227235eb176ed82706a07f3e93d25fba82616a816dc54d0c8c0695d2e68733b4"},"schema_version":"1.0","source":{"id":"1710.00335","kind":"arxiv","version":1}},"canonical_sha256":"f359b9d15c3509d16a78e36cc8b2644088155ef8cb12c3dda64a9465ae9d5f3c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f359b9d15c3509d16a78e36cc8b2644088155ef8cb12c3dda64a9465ae9d5f3c","first_computed_at":"2026-05-18T00:33:55.104702Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:33:55.104702Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"oCz28sK6J3oTfUxL5R73Mb0YaC4/ViarwfnJCrn4QLD9gUFYGbFgs/Z5FyWpg/2M2J6zu2jGTbMAdCZduwklDw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:33:55.105154Z","signed_message":"canonical_sha256_bytes"},"source_id":"1710.00335","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1b1eaa34df56fddee5d50581043ff01d61d5028449111ce7960118d79901e55e","sha256:a570822c2144c4fb6ca9926958049116df18f04fb8b572623b96ec989d7ff547"],"state_sha256":"02cec12e90018f3128ab09bd62bd2c7bddb487af2ef6a94a62cdd9fcac558481"}
