Hōʻailona hōʻailona hōʻailona

Zhi Zhang et al. mai ke Kula o ka Communication and Information Engineering, University of Electronic Science and Technology of China i hoʻolālā i ka constellation Reshaping chaotic encryption (CSCEn) scheme with statistical distribution controllable, e like me ka hōʻike ʻia ma ka FIG 2. ʻO ka mea mua, ua māhele ʻia nā ʻano hōʻailona orthogonal amplitude modulation (QAM). i loko o kekahi mau sub-sequences, a ua hana ʻia ka probabilistic shaping (PS) ma muli o ka ʻike helu helu (SI) (ma o ka hoʻololi ʻana i ka ʻāina constellation). A laila, ua hoʻopili ʻia nā kaʻina SI a hoʻopili ʻia i loko o nā ʻāpana hōʻailona chaotic me ka hoʻohana ʻana i ka algorithm mahele nui. Ua unuhi ʻia ʻo SI ma ka hopena e hoʻihoʻi i ka hōʻailona kumu [2]. Ua hoʻouna maikaʻi nā mea noiʻi i ka hōʻailona ps-16-qam i hoʻopili ʻia ma luna o kahi fiber mode single maʻamau (SSMF) o 25km. No ka mea, ʻaʻole hiki i kēia hoʻolālā ke hoʻomaopopo wale i ka hoʻonohonoho maʻalahi me ka liʻiliʻi liʻiliʻi a hoʻomaikaʻi i ka hana o ka hoʻouna ʻana a me ka loaʻa ʻana o nā hōʻailona, ​​​​akā hāʻawi pū kekahi i ka palekana e pale aku i ka hoʻouka ʻana mai ka ʻāpana ʻenehana optical illegal (ONU), e loaʻa iā ia kahi manaʻo noi maikaʻi i ka wā e hiki mai ana.
