In particular, we consider a practical scenario without instantaneous channel state information (CSI) of the eavesdropper and assume that the eavesdropping channel is a Rayleigh channel. To reduce the complexity of currently available IRS-assisted PLS schemes, we propose a low-complexity deep learning (DL) based approach to design transmitter beamforming and IRS jointly, where the precoding vector and phase s","authors_text":"Chi Zhang, Hsiao-Hwa Chen, Yiliang Liu","cross_cats":["eess.SP","math.IT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2023-04-04T10:57:24Z","title":"Deep Learning Based Joint Beamforming Design in IRS-Assisted Secure Communications"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2304.01702","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:b5658ad2ce3473062572a566f73690d6adceb0fd88481131ef989e9752e7a53c","target":"record","created_at":"2026-07-05T05:57:44Z","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":"2f43bbddb9e3022c03af622e42787ce395019a111ed396a69fb19875368700a1","cross_cats_sorted":["eess.SP","math.IT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2023-04-04T10:57:24Z","title_canon_sha256":"e15192935f3176f4650e94dbdf488a094f66b855b4789a4f1f012dba2481ffba"},"schema_version":"1.0","source":{"id":"2304.01702","kind":"arxiv","version":1}},"canonical_sha256":"371f14847b3d45cc312e09353ca61f096b1b78144f0a15fa741eb502cb8806c1","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"371f14847b3d45cc312e09353ca61f096b1b78144f0a15fa741eb502cb8806c1","first_computed_at":"2026-07-05T05:57:44.154534Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T05:57:44.154534Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"jvKivae9iI2S7LP89kCoXlaCImveFH+H99zqv1/Gwa20A6oJ6w55EkwPUT1Y+4csP0KcC9aZ36MMYOSZUsqvBA==","signature_status":"signed_v1","signed_at":"2026-07-05T05:57:44.154984Z","signed_message":"canonical_sha256_bytes"},"source_id":"2304.01702","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b5658ad2ce3473062572a566f73690d6adceb0fd88481131ef989e9752e7a53c","sha256:ce2a1eabb2d3ee07bbd18e83603bd3a79e0d106c57d4b221de9d0ad575a2a902"],"state_sha256":"2152d2e751964be6a06c72a671483b92adf4d54641cf047af29371576f52946d"}
