Ke hoʻokokoke ka helu ʻana i nā palena kino o ka wikiwiki o ka uaki, huli mākou i nā hale hoʻolālā multi-core.Ke hoʻokokoke nā kamaʻilio i nā palena kino o ka wikiwiki o ka hoʻouna ʻana, huli mākou i nā ʻōnaehana multi-antenna.He aha nā pōmaikaʻi i alakaʻi ai i nā ʻepekema a me nā ʻenekinia e koho i nā antenna he nui i kumu no 5G a me nā kamaʻilio kelepona ʻē aʻe?ʻOiai ʻo ka ʻokoʻa spatial ka kumu kumu mua no ka hoʻohui ʻana i nā antenna ma nā kahua kahua, ua ʻike ʻia i ka waena waena o 1990s ka hoʻokomo ʻana i nā antenna he nui ma ka ʻaoʻao Tx a / a i ʻole Rx i wehe i nā mea hiki ʻole ke ʻike ʻia me nā ʻōnaehana antenna hoʻokahi.E wehewehe kākou i ʻekolu mau ʻenehana nui i kēia pōʻaiapili.
**Hoʻolāʻau ʻana**
ʻO Beamforming ka ʻenehana mua kahi i hoʻokumu ʻia ai ka papa kino o nā pūnaewele kelepona 5G.ʻElua ʻano like ʻole o ka beamforming:
ʻO ka hana kukuna kahiko, ʻike ʻia hoʻi ʻo Line-of-Sight (LoS) a i ʻole ka hana kukuna kino
ʻO ka hoʻopololei nui ʻia, ʻike ʻia hoʻi ʻo Non-Line-of-Sight (NLoS) a i ʻole ka hoʻoheheʻe ʻana i nā kukui uila.
ʻO ka manaʻo ma hope o nā ʻano beamforming ʻelua, ʻo ia ka hoʻohana ʻana i nā antenna he nui e hoʻonui ai i ka ikaika hōʻailona i kahi mea hoʻohana, ʻoiai ke kāohi nei i nā hōʻailona mai nā kumu hoʻopilikia.Ma ke ʻano he hoʻohālikelike, hoʻololi nā kānana kikohoʻe i nā ʻike hōʻailona ma ke kikowaena alapine ma kahi kaʻina i kapa ʻia ke kānana spectral.Ma ke ʻano like, hoʻololi ka beamforming i nā maʻiʻo hōʻailona ma ke kikowaena spatial.ʻO ia ke kumu i kapa ʻia ai he kānana spatial.
He mōʻaukala lōʻihi ka hoʻoheheʻe kino kino i nā algorithm hoʻoponopono hōʻailona no nā ʻōnaehana sonar a me radar.Hoʻopuka ia i nā kaola maoli ma ke ākea no ka hoʻouna ʻana a i ʻole ka hoʻokipa ʻana a no laila pili pili i ke kihi o ka hōʻea ʻana (AoA) a i ʻole ke kihi o ka haʻalele ʻana (AoD) o ka hōʻailona.E like me ka hana ʻana o OFDM i nā kahawai like ʻole ma ka ʻaoʻao alapine, ʻo ka hana kuʻuna a i ʻole ka hoʻoheheʻe kino kino e hana i nā kaola like ma ka domain angular.
Ma ka ʻaoʻao ʻē aʻe, ma kāna ʻano maʻalahi loa, ʻo ka laulā a i ʻole ka beamforming virtual ʻo ia ka lawe ʻana (a i ʻole ka loaʻa ʻana) i nā hōʻailona like mai kēlā me kēia Tx (a i ʻole Rx) antenna me ka phasing kūpono a loaʻa nā paona e hoʻonui ʻia ka mana hōʻailona i kahi mea hoʻohana.ʻAʻole like me ka hoʻokele kino ʻana i kahi kaola ma kekahi ʻaoʻao, hiki i ka hoʻouna ʻana a i ʻole ka hoʻokipa ʻana ma nā ʻaoʻao a pau, akā ʻo ke kī e hoʻohui pono i nā kope he nui o ka hōʻailona ma ka ʻaoʻao e hoʻēmi i nā hopena fading multipath.
**Spatial Multiplexing**
Ma ke ʻano spatial multiplexing mode, ua māhele ʻia ke kahawai ʻikepili hoʻokomo i nā kahawai like ʻole i ka domain spatial, me kēlā me kēia kahawai a laila hoʻouna ʻia ma luna o nā kaulahao Tx like ʻole.ʻOiai ka lōʻihi o ka hiki ʻana mai o nā ala ala mai nā kihi ʻokoʻa like ʻole ma nā antenna Rx, me ka ʻaneʻane ʻaʻohe pilina, hiki i nā ʻenehana hōʻailona kikohoʻe (DSP) ke hoʻololi i kahi ʻano uila i nā ala like kūʻokoʻa.ʻO kēia ʻano MIMO ka mea nui no ka hoʻonui ʻana i ka nui o ka ʻikepili o nā ʻōnaehana uila hou, no ka mea, ua hoʻouna ʻia ka ʻike kūʻokoʻa mai nā antenna he nui ma luna o ka bandwidth like.Hoʻokaʻawale nā algorithm e like me zero forcing (ZF) i nā hōʻailona modulation mai ka hoʻopili ʻana i nā antenna ʻē aʻe.
E like me ka mea i hōʻike ʻia ma ke kiʻi, ma WiFi MU-MIMO, hoʻouna ʻia nā kahawai data he nui i nā mea hoʻohana he nui mai nā antenna hoʻouna.
**Ka Hoʻokaʻaʻike Wā-Wai**
Ma kēia ʻano, hoʻohana ʻia nā ʻōnaehana coding kūikawā i ka manawa a me nā antenna i hoʻohālikelike ʻia me nā ʻōnaehana antenna hoʻokahi, e hoʻomaikaʻi i ka loaʻa ʻana o nā hōʻailona like ʻole me ka ʻole o ka nalowale o ka helu data ma ka mea hoʻokipa.Hoʻonui nā code space-time i ka ʻokoʻa spatial me ka ʻole o ka pono no ka hoʻohālikelike ʻana i ke kahawai ma ka transmitter me nā antenna he nui.
ʻO Concept Microwave kahi mea hana loea o nā ʻāpana 5G RF no nā ʻōnaehana Antenna ma Kina, me ka kānana RF lowpass, kānana kiʻekiʻe, kānana bandpass, kānana notch/band stop filter, duplexer, Power divider and directional coupler.Hiki ke hoʻopilikino ʻia lākou a pau e like me kāu requrements.
