The received signals of the legitimate users are optimized jointly, such that their bit error ratios (BERs) are minimized and Eve's BER is significantly degraded. The emission power of randomly selected light-emitting diodes is adjusted, by exploiting users' channel state information at the transmitter. Our strategy ensures that legitimate users receive confidential messages fully in an undistorted fashion, while any meaningful leakage to Eve is strongly prohibited, without any artificial noise addition. Every user can decode only its information, hence inter-user security is also guaranteed. The PLS improvements are presented in terms of both BERs and achievable secrecy rates in practical VLC scenarios. For various user configurations, it is shown that MU-GSSK-SCD increases the BER at Eve to the 0.5 level, while providing minimized BERs to the legitimate users. The achievable secrecy rate region is derived for MU-GSSK-SCD and it is shown that full secrecy can be achieved at 0 dB signal-to-noise ratio (SNR) level with a user separation as small as 90 cm.", "publication_date": "2021-01-01", "resource_type": { "id": "publication-article", "title": { "en": "Journal article", "tr": "Dergi makalesi" } }, "rights": [ { "description": { "en": "The Creative Commons Attribution license allows re-distribution and re-use of a licensed work on the condition that the creator is appropriately credited." }, "icon": "cc-by-icon", "id": "cc-by-4.0", "props": { "scheme": "spdx", "url": "https://creativecommons.org/licenses/by/4.0/legalcode" }, "title": { "en": "Creative Commons Attribution 4.0 International" } } ], "title": "Physical Layer Security for Multi-User MIMO Visible Light Communication Systems With Generalized Space Shift Keying" }, "parent": { "access": { "owned_by": { "user": "1" } }, "communities": { "default": "be1a9c54-8a57-4004-beac-45f642d1fb86", "entries": [ { "access": { "member_policy": "open", "members_visibility": "public", "record_submission_policy": "open", "review_policy": "open", "visibility": "public" }, "children": { "allow": false }, "created": "2021-03-15T05:37:50.780180+00:00", "deletion_status": { "is_deleted": false, "status": "P" }, "id": "be1a9c54-8a57-4004-beac-45f642d1fb86", "links": {}, "metadata": { "curation_policy": "", "description": "", "page": "", "title": "TUBITAK Destekli Projelerden \u00c7\u0131kan Yay\u0131nlar Toplulu\u011fu " }, "revision_id": 0, "slug": "tubitak-destekli-proje-yayinlari", "updated": "2021-11-26T15:43:54.504251+00:00" } ], "ids": [ "be1a9c54-8a57-4004-beac-45f642d1fb86" ] }, "id": "230379", "pids": {} }, "pids": { "doi": { "identifier": "10.1109/TCOMM.2021.3050100", "provider": "external" }, "oai": { "identifier": "oai:aperta.ulakbim.gov.tr:230380", "provider": "oai" } }, "revision_id": 1, "stats": { "all_versions": { "data_volume": 3211.0, "downloads": 13, "unique_downloads": 12, "unique_views": 28, "views": 28 }, "this_version": { "data_volume": 3211.0, "downloads": 13, "unique_downloads": 12, "unique_views": 28, "views": 28 } }, "status": "published", "swh": {}, "updated": "2022-10-07T07:51:25.852038+00:00", "versions": { "index": 1, "is_latest": true } }
