Ko te tohu me te haruru i roto i te whakawhitiwhiti korero ka taea te kii he tukanga matapōkere e rereke ana i te wa.
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 tata ana te hono:①ko te tukanga matapōkere he kohinga o nga mahi tauira mutunga kore;②Ko 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-whati 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.
