How to perform the array processing in a power efficient manner is a fundamental challenge. Analog and hybrid BF require fewer analog-to-digital converters (ADCs), but can only communicate in a small number of directions at a time,limiting directional search, spatial multiplexing and control signaling. Digital BF enables flexible spatial processing, but must be operated at a low quantization resolution to ","authors_text":"Aditya Dhananjay, C.Nicolas Barati, Sourjya Dutta, Sundeep Rangan","cross_cats":["cs.NI","math.IT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2017-11-05T01:48:18Z","title":"5G Millimeter Wave Cellular System Capacity with Fully Digital Beamforming"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1711.02586","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:b78ddd93dd5b53ed0a49433b47da28d96976c88c4b5c86761c8a957ac5302627","target":"record","created_at":"2026-05-18T00:26:53Z","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":"7f6d3f58dcbfcd0c982f781a1a06809a345df5416392e3ad6bcca617d4f9ee4f","cross_cats_sorted":["cs.NI","math.IT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2017-11-05T01:48:18Z","title_canon_sha256":"d3f371d89ebaa8c9a8de85a1cc78bd4c610382772f30359ed27d8c8db5202e36"},"schema_version":"1.0","source":{"id":"1711.02586","kind":"arxiv","version":2}},"canonical_sha256":"312daa91a692b07487b76ebd3fb660d817c0dd754b96c8363241210075d6ed55","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"312daa91a692b07487b76ebd3fb660d817c0dd754b96c8363241210075d6ed55","first_computed_at":"2026-05-18T00:26:53.617615Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:26:53.617615Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"kIjXohCNgpQm/pDoOFIEFg1VAnels3SVwrGB0ommc9+rAy8Ae9t046q8jzuFOBYeT3eXg+4IAgVNv80pbikXDg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:26:53.618329Z","signed_message":"canonical_sha256_bytes"},"source_id":"1711.02586","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b78ddd93dd5b53ed0a49433b47da28d96976c88c4b5c86761c8a957ac5302627","sha256:df6b24a2c3f4c404d2b16bbecaae8d4e3ed8ae4fb0a1efdff16d2d52acd3b295"],"state_sha256":"b91a2e8ffaae71d0d929795b0cb8e72f38321eee2940d36a217bba0d76f2b573"}
