The new modulation scheme must primarily be able to achieve higher spectral efficiency than its predecessor. The main 3GPP's candidate is a new version of OFDM, called Filtered Orthogonal Frequency-Division Multiplexing (f-OFDM), which is similar to OFDM but with additional filtering in order to reduce Out-Of-Band (OOB) emissions and to obtain a better spectral-localization. Another option is windowed-OFDM (w-OFDM), which is basically a classical OFDM scheme where each ","authors_text":"Francesco Di Stasio, Fred Daneshgaran, Marina Mondin","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.SP","submitted_at":"2018-07-26T21:28:50Z","title":"Multirate 5G Downlink Performance Comparison for f-OFDM and w-OFDM Schemes with Different Numerologies"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1807.10371","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:e959d24ffdbe3d0e599272935ad3a38db1f034875f41d56c92eaeee19389aac4","target":"record","created_at":"2026-05-18T00:09:40Z","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":"7163b73e12f0f0906e48002cd592e42fd66dace0892c57520ea38fbbcf2cc139","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.SP","submitted_at":"2018-07-26T21:28:50Z","title_canon_sha256":"fff49decd2c9380fa56a741f46275388150566e1527e0fba7810996d600a6d85"},"schema_version":"1.0","source":{"id":"1807.10371","kind":"arxiv","version":1}},"canonical_sha256":"0dce54f851dfe986f46d4bca12f2d60524bbec540bb5de86214f57bea0edc0c5","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0dce54f851dfe986f46d4bca12f2d60524bbec540bb5de86214f57bea0edc0c5","first_computed_at":"2026-05-18T00:09:40.847997Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:09:40.847997Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"5J512ggSqqQlm91p8rMW8sNTg2W2xnQTOIQ3HbATqKF6ICxfSHMesf3xeGR9qKFC4gM1xvW1DA4mFBJIL6OsBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:09:40.848702Z","signed_message":"canonical_sha256_bytes"},"source_id":"1807.10371","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e959d24ffdbe3d0e599272935ad3a38db1f034875f41d56c92eaeee19389aac4","sha256:5f230aa0c4e4d058c15187788be053f8724997f351e1d21cf13e6f9bb33dd44b"],"state_sha256":"3aebbe863d36b94a2f87ff834e8dbfb3a207501c470ec0940f5ea7d107205426"}
