Wideband Digital Receiver

Kuboneka kwachintu

Kuyanda kwabasikuula

I. Makani aamulimo
Chengdu XST Microwave Communication Co., Ltd, mbuli musololi mumulimo wa RF microwave akukwabilila magesi, wakalyaaba kukuchita zintu zipya akusumpula zintu kuchitila kuti azuzikizye ziyandikana zyabantu. Alimwi XST, mbuli inkamu iisololela mukupanga akupanga zibelesyo zyakubelesya muma microwave, yakapa zintu zibotu loko kuli basikuula biingi antoomwe akuyobolola kwayo kupati mumulimo wazibelesyo zyakutambula azibelesyo zyakutambula. Ooku kubelekela antoomwe kulaa makanze aakuswaanganya bubotu bwabaabo boonse bobile kuti bape nzila zisumpukide zyakubelesya minchina yaku Chengdu XST Microwave Communication Co., Ltd. antoomwe akusumpula kuyaambele kwatekkinoloji yakutambula minchina.
II. Nzila yakubelesya
Kuzwa kumatalikilo aapulojekiti, XST yakazumanana kubandika akubelekela antoomwe a Chengdu Xike Microwave Communication Co. Twakamvwisisisya nzyobakali kuyanda basikuula mpawo twakamvwisisisya twaambo toonse kuchitila kuti pulojekiti ichitwe kabotu. Kakuli luzibo lwa XST lwamyaka minji mukubamba akupanga zibelesyo zyakutambula, twakabamba zibelesyo zyakutambula zya dijitali zya Chengdu Xike zili abubotu bwakumvwisisisya, kululama, kukkalikana, kubamba zintu munzila iikonzya kuchincha akukonzya kubelesya milimu iikatazya kumvwisisisya.
Muchiindi chakubelesya pulojekiti, tubikkila maanu kukuyanzana akusandula abasikuula. Kubusena buli boonse bwakubamba, tulaa mibandi mipati abasikuula kuchitila kuti nzila yakubamba ikonzye kuzuzikizya ziyandikana zyabasikuula. Aawo awo, tulapa lugwasyo lwazyakuchita akuyiisya basikuula kuti tubagwasye kumvwisisisya akubelesya zintu zyesu.
III. Lugwasyo lwamulimu
Kuti tubone kuti basikuula balakonzya kujana luzibo luli kabotu mukubelesya, tulapa lugwasyo luzulide lwazyabusongo alugwasyo lwamana kuula. Mukuyungizya, tulapa basikuula mulimo wakubambulula akubambulula lyoonse kuchitila kuti zibelesyo zyakutambula zibelesyegwe kabotu kwachiindi chilamfu. Kabunga kesu kabelekela bantu nibakamana kuula lyoonse kalilibambilide, kalilibambilide kugwasya basikuula lugwasyo lwachiindi chifwiifwi alulayo lwazyakuchita.

Kwiinda mukubelekela antoomwe ooku, tulimvwa loko mbociyandika kubelekela antoomwe abasikuula besu. Kumpela, tunoozumanana kusumpula muzeezo wa 'kubikkila maanu kubasikuula' kuti tupe basikuula zintu zibotu alimwi zibeleka obotu. Aawo awo, tulangilila kubeleka ababelesinyina banji kuti tusumpule antoomwe kuyaambele akupanga zintu zipya zyakubelesya minchina yakwaambuuzyania.

Zibeela Zyachintu

20MHz ~ 3.3GHz nzila yakutambula majwi
Kuchincha kwa digital IF bandwidth kusika ku 20MHz
Kulekkooda kwa I/Q kusikila ku 500kHz, ikuzumizya kubamba twaambo kakunyina intaneti
Igwasyilizya kugwisya zitondezyo zya AM/FM mpawo ipa nzila yakuswiilila majwi.
Kubamba zitondezyo kupa kuti cikonzyeke kulanga-langa, kubamba akujana zitondezyo zyachiindi chifwiifwi naakuti zintu zinyonganya
LAN interface yakweendelezya kule akugwisya data
API ilembedwe kabotu yakubamba mapulogilamu naakuti kubamba ma aapulikesheni.
Kubelesya manguzu masyoonto, kulema kuuba akuba muniini zipa kuti kibe chintu chibotu mukuswaanganya akubikkwa.

Zibelesyo

• Basikutambula bazike mumabambe aajatikizyidwe aakugwisya nzila zyakubelesya akulanga zyintu zyiingi
• Kuziba zitondezyo zinyonganya mumugwagwa, kugwasya sikubelesya kuti afwambaane kugwisya zintu zinyonganya
• Kulanga-langa milimo ya wailesi yababelesi akulanga-langa mweelwe mupati wa milimo ya wailesi munzila ziindene-indene zyakuskena
• Zibelesyo zyakutambula zyabazike zyabaabo babelesya nzila zyakubandika, eezyo zikonzya kubamba data ya baseband ya narrowband channels muchiindi cheenzu
• Kuzyiba zibelesyo zisyoonto zyakutumizya makani, kubelesya nzila ya differential spectrum function kujana zibelesyo zyakuswiilila zya radio zisyoonto
