By utilizing the transform relationships between the delay-sequency (DS), time-frequency (TF) and time-domains, we first conceive the DS-domain input-output relationship of our OTSM system, where the conventional zero-padding is discarded to increase the spectral efficiency. Then, the unconditional pairwise error probability is derived, followed by deriving the bit error ratio (BER) upper bound in closed-form. Moreover, we compare the BER performance ","authors_text":"Hien Quoc Ngo, Hongming Zhang, Lajos Hanzo, Michail Matthaiou, Zeping Sui","cross_cats":["eess.SP","math.IT"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.IT","submitted_at":"2024-02-01T21:27:16Z","title":"On the BER vs. Bandwidth-Efficiency Trade-offs in Windowed OTSM Dispensing with Zero-Padding"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2402.01024","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":"sha256:66a44b604c2e745a446543cf746f5e26fbdaa3f71509f9b26966e065c3a0d5b4","target":"record","created_at":"2026-07-05T07:40:29Z","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":"657b8859c988631d096454bc4dd7f8df418f33c6fad4108078aac206107d1c1e","cross_cats_sorted":["eess.SP","math.IT"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.IT","submitted_at":"2024-02-01T21:27:16Z","title_canon_sha256":"d12b6a4d9d0234637335e3c349d012b7d6375084966a867c3ce267f287d3f5d2"},"schema_version":"1.0","source":{"id":"2402.01024","kind":"arxiv","version":1}},"canonical_sha256":"2b9acc6218bafbf053e410826288b58e11e4ea70baa82d813c8aed972557adb4","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2b9acc6218bafbf053e410826288b58e11e4ea70baa82d813c8aed972557adb4","first_computed_at":"2026-07-05T07:40:29.523825Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T07:40:29.523825Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"CqHSbh3sqsKoCiAp58X3MRC5NZzBJZjM1cko+tFOt39PchJ7weYaYAfCKkoPbxES6tBk1iqlCy9LFwixnsiWCw==","signature_status":"signed_v1","signed_at":"2026-07-05T07:40:29.524240Z","signed_message":"canonical_sha256_bytes"},"source_id":"2402.01024","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:66a44b604c2e745a446543cf746f5e26fbdaa3f71509f9b26966e065c3a0d5b4","sha256:be10de228c1c2217af4574fdd634efed8b7a85800ee242eb7df634ca681e658d"],"state_sha256":"b577f2fde1cd815fa1f66fcc71d1e7121bc8f4f0aa28c2d23f6a3d314bc19ef5"}
