MICROCHIP Costas Loop Whakahaere Kaiwhakamahi Aratohu
Kupu Whakataki
I roto i te whakawhiti ahokore, ka wehea te Kaituku (Tx) me te Kaiwhiwhi (Rx) e te tawhiti me te wehe hiko. Ahakoa ko te Tx me te Rx e hono ana ki te auau kotahi, he rereke te auau i waenga i nga iarere kawe na te rereketanga o te ppm i waenga i nga oscillator e whakamahia ana i roto i te Tx me te Rx. Ka utuhia te auautanga ma te whakamahi i nga tikanga tukutahi awhina raraunga, kore-raraunga ranei (matapo).
Ko te Costas Loop he tikanga PLL-kore-raunga-awhina mo te utu utu utunga auau kawe. Ko te tono tuatahi o Costas koropiko kei roto i nga kaiwhiwhi ahokore. Ma te whakamahi i tenei, ka utua te auau i waenga i te Tx me te Rx me te kore awhina o nga oro pairati, tohu ranei. Kua whakatinanahia te Costas Loop mo te BPSK me te QPSK modulations me te huringa o te paraka tatauranga hapa. Ma te whakamahi i te Costas Loop mo te wahanga, te tukutahi auau ka puta pea te rangirua o te wahanga, me whakatika ma nga tikanga penei i te whakawaehere rereke.
