Kutaurirana kwesatellite kunoita basa rakakosha mukushandiswa kwemazuva ano kwemauto nevanhuwo zvavo, asi mukana wayo wekukanganiswa wakakonzera kugadzirwa kwenzira dzakasiyana siyana dzekudzivirira kuvharwa kwedata. Chinyorwa chino chinopfupikisa matekinoroji matanhatu akakosha ekune dzimwe nyika: kupararira kwesimba, kunyora nekushandura makodhi, kudzivirira kuvharwa kwedata, kugadzirisa mashandisirwo edata, kugadzirisa mashandisirwo edata, uye kugadzirisa mashandisirwo edata, pamwe chete nematekiniki ekubatanidza data, kuongorora misimboti nemashandisirwo azvo.
1. Tekinoroji yeSpread Spectrum
Spread spectrum inowedzera kugona kwekudzivirira jamming nekuwedzera bandwidth yesignal, zvichideredza simba respectral density. Direct Sequence Spread Spectrum (DSSS) inoshandisa pseudo-random codes kuwedzera bandwidth yesignal, ichiparadzira simba re narrowband interference. Izvi zvakakosha mukukurukurirana kwesatellite yemauto, kudzivirira jamming nemaune (semuenzaniso, co-frequency kana broadband noise interference) kuti ive nechokwadi chekuti kuraira neruzivo zvakachengeteka.
2. Tekinoroji yeCoding uye Modulation
Makodhi ekugadzirisa zvikanganiso epamusoro (semuenzaniso, makodhi eTurbo, LDPC) pamwe chete nekuchinja kwehurongwa hwepamusoro (semuenzaniso, PSK, QAM) anovandudza kushanda zvakanaka kwespectral uku achideredza zvikanganiso zvinokonzerwa nekupindira. Semuenzaniso, LDPC ine QAM yepamusoro inovandudza masevhisi esatellite ekutengeserana (semuenzaniso, HDTV, internet) uye inoita kuti kutaurirana kwemauto kuve kwakasimba munzvimbo dzinokwikwidzana.
3. Tekinoroji yeAntena Inodzivirira Kuvharika kweMakamera
Maantenna anochinjika uye akangwara anogadzirisa mapatani emwenje kuti abvise majammer. Maantenna anochinjika anochinjika anotungamira ma nulls kune zvinokanganisa, nepo maantenna akangwara achishandisa multi-array processing yekusefa nzvimbo. Izvi zvakakosha muSATCOM yemauto kurwisa njodzi dzehondo dzemagetsi.
4. Tekinoroji Yekugadzirisa Zviri Muchikepe (OBP)
OBP inoita basa rekubvisa masaini, kubvisa makodhi, uye kutumira zvakananga pamasetiraiti, zvichideredza kushaya simba kwekutumira masaini pasi. Mashandisirwo emauto anosanganisira kugadzirisa kwakachengeteka munharaunda kudzivirira kuteererwa kwemashoko uye kugovera zviwanikwa kuti zvishande zvakanaka.
5. Kugadziriswa kweTransform-Domain
Matekiniki akaita seFFT uye wavelet anoshandura masaini kuita ma frequency kana kuti time-frequency domains kuti asvine interference filtering. Izvi zvinorwisa broadband uye jamming inosiyana-siyana, zvichivandudza kuchinjika munzvimbo dzakaoma dzemagetsi.
6. Kugadziriswa kweAmplitude-Domain
Zvimisikidzo uye Automatic Gain Control (AGC) zvinodzivisa kupindira kwakasimba kwemhepo (semuenzaniso, mheni kana kudzvanya kwemuvengi), kuchengetedza maseketi ekugamuchira uye kuchengetedza kugadzikana kwezvinobatanidza.
7. Tekinoroji yeAdaptive Link
Kugadziriswa kwekodhi, modulation, uye data rates panguva chaiyo zvichienderana nemamiriro echiteshi (semuenzaniso, SNR, BER) kunoita kuti pave nekutaurirana kwakavimbika pasinei nemamiriro ekunze kana kusagadzikana. Masisitimu emauto anoshandisa izvi kuti agone kusimba mumamiriro ehondo anochinja-chinja.
Mhedziso
Matekinoroji ekunze ekudzivirira kuvharika kwedata anoshandisa nzira dzakasiyana-siyana dzinosanganisira kugadzirisa masaini, kunyora makodhi, uye masisitimu anochinjika. Kushandiswa kwemauto kunonyanya kukosha kusimba nekuchengetedzwa, ukuwo mashandisirwo ekutengeserana achitarisa pakushanda zvakanaka. Kufambira mberi mune ramangwana kunogona kubatanidza AI nekugadzirisa panguva chaiyo kuti kurwise njodzi dziri kuchinja.
Chengdu Concept Microwave Technology CO.,Ltd inyanzvi yekugadzira zvikamu zve5G/6G RF zvekutaurirana nesatellite muChina, zvinosanganisira RF lowpass filter, highpass filter, bandpass filter, notch filter/band stop filter, duplexer, Power divider uye directional coupler. Zvese zvinogona kugadziriswa zvichienderana nezvaunoda.
