Nā hiʻohiʻona:
- Haʻahaʻa hoʻololi poho
- Kaʻawale Kiʻekiʻe
1. Hāʻawi i ka ʻike o ka pae a me ka amplitude: Ma muli o ka hoʻopili ʻana o nā kahawai I a me Q, hiki i ka hui hui IQ ke hāʻawi i nā ʻike ʻelua a me ka amplitude o ka hōʻailona. He mea koʻikoʻi kēia no nā ʻōnaehana kamaʻilio uila a me nā kaʻina modulation a me demodulation.
2. Hoʻomaopopo i ka hana hōʻailona orthogonal: Hiki i nā ala I a me Q o ka hui hui IQ ke hana i nā hōʻailona orthogonal, ʻo ia hoʻi, nā hōʻailona me kahi ʻokoʻa o ka pae o 90 degere. Hoʻohana nui kēia i nā ʻenehana modulation a me demodulation, e like me ka orthogonal frequency division multiple access (OFDM) a me ka quadrature amplitude modulation (QAM).
3. Hoʻemi ʻia ka hoʻolohe hoʻolohe: hiki i ka hui hui IQ ke hoʻokaʻawale i ka hōʻailona a me ke ʻano o ka hoʻopili ʻana ma muli o ka hoʻokomo ʻana o ʻelua mau ala hoʻohui. ʻO kēia ka mea hiki iā ia ke pale aku i ke keakea eavesdropping.
4. Kiʻekiʻe dynamic range: Ma muli o ka hoʻohana ʻana i ʻelua awāwa, ʻo nā hui hui IQ maʻamau i kahi kiʻekiʻe kiʻekiʻe e hiki ai ke hoʻokō i nā noi hoʻoili hōʻailona koi.
1.Nūnaewele kamaʻilio ʻole: Hoʻohana nui ʻia ka IQ mixer i nā ʻōnaehana kamaʻilio kelepona, me nā ʻōnaehana kelepona kelepona, nā ʻōnaehana kelepona ukali a me nā ʻupena kūloko kūloko. Hoʻohana ʻia ia e demodulate i ka hōʻailona i loaʻa, hoʻololi i ka hōʻailona i hoʻouna ʻia, a ʻike i ka demodulation, modulation a me ka hoʻololi pinepine ʻana o ka hōʻailona.
2.Modem: ʻO nā mea hui IQ nā mea nui i loaʻa maʻamau i nā modem i hoʻohana ʻia e hoʻohui i nā hōʻailona baseband i loko o ka laulā RF no ka hoʻouna ʻana, a i ʻole e hui pū i nā hōʻailona RF i loaʻa i ka baseband no ka demodulation.
3.High-speed data transmission: No ka mea hiki i nā hui hui IQ ke hoʻopaʻa i nā hōʻailona orthogonal, loaʻa iā lākou nā noi koʻikoʻi i ka hoʻoili ʻikepili kiʻekiʻe. No ka laʻana, i nā ʻōnaehana kamaʻilio optical a me nā kamaʻilio kikohoʻe kiʻekiʻe, ka modulation QAM a me ka demodulation me ka hoʻohana ʻana i nā hui IQ hiki ke hiki ke hoʻouna i ka ʻikepili kiʻekiʻe a me ka nui.
4.Carrier interference analysis: Hiki ke hoʻohana ʻia nā huila IQ no ka nānā ʻana i ka hoʻopili ʻana i ka mea lawe, hiki ke kōkua i ka hoʻoholo ʻana i ke kumu o ke keakea a hoʻopau i ka hoʻopili ʻana ma ke ana ʻana a me ka nānā ʻana i ka ʻikepili a me ka amplitude o ka hōʻailona.
