To evaluate the efficiency of PAPR-reducing methods, the complementary cumulative distribution function (CCDF) of PAPR is often used. In the situation where the central limit theorem can be applied, an approximate form of the CCDF has been obtained. On the other hand, in general situations, the bound of the CCDF has been obtained under some assumptions. In this paper, we derive the bound of the CCDF with no assumption about modulation schemes. Therefore, our bound can be applied with any codewords and that our b","authors_text":"Hirofumi Tsuda","cross_cats":["math.IT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2019-02-18T06:45:14Z","title":"Moment-Based Bound on Peak-to-Average Power Ratio and Reduction with Unitary Matrix"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1902.06420","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":"sha256:65e886654839c0f2d2701c0e7b005d5288f07c3c413fb819f99ad44c23db4d87","target":"record","created_at":"2026-05-17T23:53:45Z","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":"df485789a28c9ef2e238a69723c7c2287f36483b38b2bd5038db2e870d7b1406","cross_cats_sorted":["math.IT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2019-02-18T06:45:14Z","title_canon_sha256":"3ab937e703d9174c936b328a9c5016625abbba4b81589a2ef50cad42263b9d85"},"schema_version":"1.0","source":{"id":"1902.06420","kind":"arxiv","version":1}},"canonical_sha256":"853a11bf89fa30a531f477941efdb7b8dceff7fdd2acc0f2c81958d1d47886c7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"853a11bf89fa30a531f477941efdb7b8dceff7fdd2acc0f2c81958d1d47886c7","first_computed_at":"2026-05-17T23:53:45.558989Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:53:45.558989Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"8hyrmnxUTyZJZxdiMQVDgIKxBPU/HM6th6TnUX2bPnmw1nJUREMEaSYF4Ubn8fDA46lmwfe4i/XGbW6beveLCw==","signature_status":"signed_v1","signed_at":"2026-05-17T23:53:45.559464Z","signed_message":"canonical_sha256_bytes"},"source_id":"1902.06420","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:65e886654839c0f2d2701c0e7b005d5288f07c3c413fb819f99ad44c23db4d87","sha256:33fb3d16b4ee3e5757a5df894dfc53e07b982afc626770ae71e9accfe307a682"],"state_sha256":"2fc9b4606fae8c91595b82696bed14d09f8d52b3fd836d9a47ac6acc8f048031"}
