Rather than suppressing interference as in conventional schemes, we take advantage of constructive interference among users, inherent in the downlink, as a source of both useful information and wireless energy. Specifically, we propose a new precoding design that minimizes the transmit power while guaranteeing the quality of service (QoS) and energy harvesting constraints for generic phase shift keying modulated","authors_text":"Christos Masouros, Gan Zheng, Ioannis Krikidis, Stelios Timotheou","cross_cats":["math.IT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2015-01-16T13:54:06Z","title":"Exploring Green Interference Power for Wireless Information and Energy Transfer in the MISO Downlink"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1501.03982","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:ea83760e62c8d1012ab216b1bbc2987b51325bb5e5c07a9d7b90c9a2ae4f8967","target":"record","created_at":"2026-05-18T02:29:16Z","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":"08a6c531b31f1bbffd14f4c5381092a6272c49890a87b71bfd434d8b9fe7ecde","cross_cats_sorted":["math.IT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2015-01-16T13:54:06Z","title_canon_sha256":"b5c9d2f6f1065e8a5319b19372af8d320896c62abc6d09f02eae3b4062d8815d"},"schema_version":"1.0","source":{"id":"1501.03982","kind":"arxiv","version":1}},"canonical_sha256":"02cc990f557600df499845bb7f64969360ab5fba2a5d5d1a0d758fd1932d02a7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"02cc990f557600df499845bb7f64969360ab5fba2a5d5d1a0d758fd1932d02a7","first_computed_at":"2026-05-18T02:29:16.588391Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:29:16.588391Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"SDhxdWUCH3F7CdVGqkCKFGzsJ/hldrlYFINxb/VXxC58CdtvYYBoOt2ZCMiKbmHbBsw3mMtqCLZTjTYZvlh9Bg==","signature_status":"signed_v1","signed_at":"2026-05-18T02:29:16.588832Z","signed_message":"canonical_sha256_bytes"},"source_id":"1501.03982","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ea83760e62c8d1012ab216b1bbc2987b51325bb5e5c07a9d7b90c9a2ae4f8967","sha256:f70a91b6994c3cc1bdf0a62082147bce0b6bc743462c080163636ff58aa263b8"],"state_sha256":"ed241c572c51c90367b0b3a5b3da6f8f50068f53c168deb617c8d2c1b560a68e"}
