    Tukatuka Matapōkere o te Pūnaha Whakawhitiwhiti

    Wā tuku: Akuhata-22-2022

    Ko te tohu me te haruru i roto i te whakawhitiwhiti korero ka taea te kii he tukanga tupurangi e rereke ana i te waa.
    Ko te tukanga matapōkere he āhuatanga o te taurangi matapōkere me te mahi taima, ka taea te whakaahua mai i nga tirohanga rereke e rua engari e piri ana:ko te tukanga matapōkere he kohinga o nga mahi tauira mutunga kore;Ko te tukanga matapōkere he huinga taurangi matapōkere.

    Ko nga ahuatanga tauanga o te tukanga matapōkere e whakaahuatia ana e tana taumahi toha, te mahi kiato tūponotanga ranei. Mēnā he motuhake ngā āhuatanga tauanga o tētahi hātepe matapōkere i te wā tīmata, ka kīia he hātepe tino pūmau.
    Ko nga ahuatanga matihiko tetahi atu huarahi poto ki te whakaahua i nga tukanga matapōkere. Mēnā he pūmau te wāriu toharite o te hātepe, ā, ko te mahi autocorrelation R (T1, T1+ τ)= R (T), ka kīia te hātepe he hātepe pūmau whānui.

    Mēnā he pūmau te hātepe, me tino pūmau tonu; ki te kore, kare pea i te pono.Mēnā he rite te wā toharite o tētahi hātepe ki te tauwaenga tauanga hāngai, he hāneanea te hātepe.Mēnā he hāneanea te hātepe, he pūmau hoki; ki te kore, kare pea i te pono.

    Ko te taumahinga autocorrelation R (T) o te tukanga noho noa he taurite o te rereketanga o te wa R, a ko te R (0) he rite ki te katoa o te hiko toharite, ko te R( τ) te uara teitei. Ko te kiato hiohio hiko (P) ξ (f) ko te mahi honohono aunoa o te huringa Fourier R() (Wiener Minchin theorem). Ko enei huringa takirua e whakatau ana i te hononga whakawhiti i waenga i te waa me te waahi auau. Ko te tuari tūponotanga o te hātepe Gaussian e whai ana i te tohatoha noa, a ko tana whakaahuatanga tauanga katoa e hiahia ana ko ona ahuatanga tau anake. Ko te tohatoha tūponotanga ahu-tahi anake e whakawhirinaki ana ki te toharite me te rerekee, ko te tohatoha tūponotanga ahu-rua te nuinga ka whakawhirinaki ki te mahi honohono. Ko te tukanga Gaussian he tukanga Gaussian tonu i muri i te huringa raina. Ko te hononga i waenga i te mahi tohatoha noa me te mahi Q (x) ranei ERF (x) he tino whai hua ki te tātari i te mahi aukati haruru o nga punaha korero mamati. He tukanga stochastic e noho ana I muri i te haere a I (T) i roto i te punaha raina, ka pumau ano te tukanga whakaputa ξ 0 (T).

    Ko nga ahuatanga tauanga o nga tukanga matapōkere-rua me nga ngaru hiko me te haruru Gaussian nati-band he pai ake mo te tātari i nga punaha whakarereke, nga punaha roopu-pae, me te whakawhitiwhiti ahokore nga hongere ara maha. Ko nga tohatoha noa e toru i roto i te whakawhitiwhiti korero ko te tohatoha Rayleigh, te tohatoha raihi, me te tohatoha noa: te kopaki o te tohu kawe sinusoidal me te whaaiti. Ko te haruru Gaussian te tikanga he tohatoha raihi. A, no te he nui te kaha tīwera tohu, ahu te reira ki te tohatoha noa; ina he iti te kaha kaha, he tata ki te tohatoha Rayleigh.

    Ko te haruru ma Gaussian he tauira pai ki te tātari i te haruru taapiri o te hongere, a ko te puna haruru nui o te haruru waiariki korero no tenei momo haruru. Ko ona uara i nga wa rereke e rua kaore i te hono me te motuhake o te tatauranga. I muri i te paahitanga o te haruru ma i roto i te punaha roopu-iti, ko te hua ko te haruru roopu-iti. Ko te haruru ma te iti me te haruru ma te bandpass he mea noa i roto i te tātaritanga ariā.

    Ko runga ake nei ko te tuhinga "te tukanga tupurangi o te punaha korero" i kawea mai e Shenzhen HDV phoelectron Technology Co., Ltd. ko te tumanako ka awhina tenei tuhinga ki a koe ki te whakanui ake i to matauranga. I tua atu i tenei tuhinga mena kei te rapu koe i tetahi kamupene kaihanga taputapu korero muka whatu pai ka whakaarohia e koemo tatou.

    Ko Shenzhen HDV phoelectron Technology Co., Ltd. te nuinga o te kaihanga o nga hua korero. I tenei wa, ko nga taputapu i hangaia e hipoki ana i teONU raupapa, raupapa kōwae whatu, raupapa OLT, araupapa transceiver. Ka taea e matou te whakarato ratonga motuhake mo nga ahuatanga rereke. Tena koekorero.
