He mea nui te whakawhitiwhiti kōrero amiorangi i roto i ngā mahi hōia me ngā mahi ā-iwi o ēnei rā, engari nā tōna ngāwari ki te pokanoa kua akiaki i te whanaketanga o ngā tikanga ārai-aukati. E whakarāpopoto ana tēnei tuhinga i ngā hangarau matua e ono o tāwāhi: te horapa o te whānuitanga, te waehere me te whakarerekētanga, te ārai-aukati pūihi, te tukatuka i runga i te papa, te tukatuka rohe-whakawhiti, me te tukatuka rohe-kaha, me ngā tikanga hononga urutau, te tātari i ō rātou mātāpono me ngā tono.
1. Hangarau Whānuitanga?
Ka whakarei ake te whānuitanga horapa i te kaha ārai-aukati mā te whakawhānui i te whānui o te tohu, me te whakaiti i te kiato o te kaha o te hihi. Ka whakamahia e te Whānuitanga Raupapa Tika (DSSS) ngā waehere rūpahu-matapōkere hei whakawhānui i te whānui o te tohu, hei whakamarara i te kaha pokanoa whāiti. He mea nui tēnei i roto i ngā whakawhitiwhitinga amiorangi hōia, hei ārai i te aukati ā-taurangi (hei tauira, te pokanoa auau-tahi, te pokanoa haruru whānui rānei) hei whakarite i te tuku whakahau me te mōhiohio haumaru.
2. Hangarau Whakawaehere me te Whakarerekētanga?
Mā ngā waehere whakatika hapa matatau (hei tauira, ngā waehere Turbo, LDPC) me te whakarerekētanga taumata-teitei (hei tauira, PSK, QAM) ka whakapai ake i te whai huatanga o te hihi, me te whakaiti i ngā hapa i puta mai i te pokanoa. Hei tauira, mā te LDPC me te QAM taumata-teitei ka whakarei ake i ngā ratonga amiorangi arumoni (hei tauira, HDTV, ipurangi) ā, ka whakarite kia pakari te whakawhitiwhiti kōrero hōia i roto i ngā taiao tautohetohe.
3. Hangarau Ārai-Whakararu Pūihi?
Ka whakarerekē hihiri ngā pūihi urutau me ngā pūihi atamai i ngā tauira hihi hei whakakore i ngā mea aukati. Ka ārahi ngā pūihi urutau i ngā kore ki ngā pūtake pokanoa, ko ngā pūihi atamai ia ka whakamahi i te tukatuka maha-huinga hei tātari ā-wāhi. He mea nui ēnei i roto i te SATCOM hōia hei ārai i ngā tūmomo pakanga hiko.
4. Hangarau Tukatuka-ā-Poari (OBP)?
Ka whakahaerehia e OBP te wetewete tohu, te wetewaehere, me te ara tika i runga i ngā amiorangi, ka whakaiti i ngā ngoikoretanga o te tuku kōrero whenua. Kei roto i ngā tono hōia ko te tukatuka ā-rohe haumaru hei ārai i te whakarongo puku me te tohatoha rauemi kua whakapaitia kia pai ai te whai hua.
5. Te Tukatuka Rohe-Whakawhiti?
Mā ngā tikanga pēnei i te FFT me te whakawhiti ngaruiti ka huri i ngā tohu ki ngā rohe auau, ki ngā rohe auau-wā rānei hei tātari i ngā pokanoa. Ka ārai tēnei i te whānui o te raraunga me te aukati i te rerekētanga-wā, ka whakapai ake i te urutau i roto i ngā taiao hikohiko uaua.
6. Te Tukatuka Rohe-Whānui?
Ka pehia e ngā here me te Mana Whakanui Aunoa (AGC) ngā wawaotanga kaha ā-whakaaro (hei tauira, te uira, te aukati rānei a te hoariri), ka tiakina ngā ara iahiko kaiwhiwhi me te pupuri i te pumau o te hononga.
7. Hangarau Hononga Urutau?
Mā ngā whakarerekētanga wā-tūturu ki te waehere, te whakarerekētanga, me ngā tere raraunga i runga i ngā āhuatanga o te hongere (hei tauira, SNR, BER) ka whakarite kia pono te whakawhitiwhiti kōrero ahakoa te āhuarangi, te aukati rānei. Ka whakamahia tēnei e ngā pūnaha hōia hei whakapakari i te manawa i roto i ngā horopaki pakanga hihiri.
Whakamutunga?
Ka whakamahia e ngā hangarau ārai-aukati o tāwāhi ngā huarahi maha-paparanga e kapi ana i te tukatuka tohu, te waehere, me ngā pūnaha urutau. Ko te whakamahinga hōia he mea nui ki te pakari me te haumarutanga, ko ngā tono arumoni ia e aro ana ki te whai huatanga. Tērā pea ka whakauruhia e ngā whanaketanga ā muri ake nei te AI me te tukatuka wā-tūturu hei ārai i ngā tūmomo riri e whanake haere ana.
