Likaroloana:
- Tahlehelo e tlase ea Phetoho
- Ho Ikhetha ho Phahameng
1. Fana ka tlhahisoleseding ea karolo le ea amplitude: Ka lebaka la ho kenyelletsoa ha likanale tsa I le Q, IQ mixer e ka fana ka tlhahisoleseding ea bobeli le ea amplitude ea pontšo. Sena ke sa bohlokoa bakeng sa mekhoa e mengata ea puisano e se nang mohala le mekhoa ea ho feto-fetoha le maemo.
2. Lemoha ts'ebetso ea matšoao a orthogonal: Liteishene tsa I le Q tsa IQ mixer li khona ho sebetsana le matšoao a orthogonal, ke hore, lipontšo tse nang le phapang ea karolo ea 90 degrees. Sena se etsa hore e be molemo haholo mekhoeng e mengata ea ho feto-fetoha le maemo, joalo ka orthogonal frequency division multiple access (OFDM) le quadrature amplitude modulation (QAM).
3. Ho fokotsa ho kena-kenana ha ho mamela: Motsoako oa IQ o khona ho arola pontšo ea pontšo le tšitiso ka lebaka la ho kenyelletsoa ha litsela tse peli tse tlatsetsang. Sena se etsa hore e khone ho thibela ho kena-kenana le batho ba mamelang.
4. Boemo bo phahameng bo matla: Ka lebaka la tšebeliso ea likanale tse peli, li-mixer tsa IQ ka tloaelo li na le mefuta e mengata e matla e ka kopanang le lits'ebetso tse hlokahalang tsa ho sebetsana le matšoao.
1.Mekhoa ea puisano e se nang mohala: IQ mixer e sebelisoa haholo mekhoeng ea puisano e se nang mohala, ho kenyeletsoa mekhoa ea puisano ea mehala, mekhoa ea puisano ea sathelaete le marang-rang a sebaka se se nang mohala. E sebelisoa ho theola lets'oao le amohetsoeng, ho hlophisa lets'oao le rometsoeng, le ho hlokomela ho theoleloa, ho feto-fetoha ha molumo le phetolo ea khafetsa ea lets'oao.
2.Modem: Li-mixer tsa IQ ke likarolo tsa bohlokoa tse fumanehang hangata ho modem tse sebelisetsoang ho kopanya matshwao a baseband mofuteng oa RF bakeng sa ho fetisoa, kapa ho kopanya matshwao a RF a amoheloang ho baseband bakeng sa ho theola batho.
3.Phetiso ea data e potlakileng: Hobane li-mixer tsa IQ li khona ho sebetsana le matšoao a orthogonal, li na le likopo tsa bohlokoa ho fetisetsoang ha data ka lebelo le phahameng. Ka mohlala, mekhoeng ea puisano ea optical le puisano e potlakileng ea dijithale, QAM modulation le demodulation ho sebelisa IQ mixers ka etsa hore ho fetisoa ha data ka lebelo le phahameng le le phahameng.
Tlhahlobo ea ho kena-kenana le 4.Carrier Carrier: Li-mixer tsa IQ li ka sebelisoa bakeng sa tlhahlobo ea ho kena-kenana le bajari, e ka thusang ho fumana mohloli oa ho kena-kenana le ho felisa ho kena-kenana ka ho lekanya le ho hlahloba lintlha tsa mohato le amplitude ea pontšo.
