I-Laser Remote Speech Detection Signal Ukuhlaziywa nokucutshungulwa

I-laserUkuhlaziywa kwesiginali yesiginali yenkulumo ekude nokucutshungulwa
Ukudonswa komsindo wesiginali: Ukuhlaziywa kwesiginali nokucutshungulwa kokutholwa kwenkulumo ye-laser Remote Speech
Emisebeni ye-Wondrous of Technology, ukutholwa kwenkulumo ye-laser Remote Halt kufana ne-symphony enhle, kepha le symphony nayo inomsindo wayo "umsindo" - umsindo wesiginali. Njengezithameli ezinomsindo ongalindelekanga ekhonsathini, umsindo uvame ukuphazamisaUkutholwa kwenkulumo yeLaser. Ngokusho komthombo, umsindo wokutholwa kwesiginali yesikhathi se-laser Remote Humusoal ungahlukaniswa umsindo owethulwe yithuluzi lokulinganisa le-laser vibration uqobo, umsindo owethulwe yiminye imithombo eseduze nelitshe le-vibration eduze kwelitshe le-vibration kanye nomsindo okhiqizwe ukuphazamiseka kwemvelo. Ekugcineni ukutholakala kwenkulumo ede kudinga ukuthola amasiginali okukhuluma angabonakala ngokuzwa komuntu noma imishini eminingi ehlanganisiwe evela endaweni yokuxhumana etholakele, futhi uhlelo lokutholwa lwemvamisa luzokwehlisa ukusatshalaliswa kwe-frequency band yesiginali yenkulumo (cishe ngo-300 ~ 3000 Hz). Akunakuhlungwa nje yizihlungi zendabuko, futhi ukucutshungulwa okwengeziwe kwezimpawu zokukhuluma ezitholakele kuyadingeka. Njengamanje, abacwaningi bafunda kakhulu i-Denoising of non-stationary umgadli we-Broadband nomsindo.
Umsindo wasemuva weBroadband ucubungulwa ngokuvamile yindlela yokulinganisa yesikhathi esifushane, indlela yokufaka kanye nezinye izindlela zokucindezela ngomsindo ezisuselwa ekusebenzeni kwesiginali, kanye nezindlela zokufunda zomshini wendabuko, izindlela zokufunda okujulile kanye nezinye izinkulumo zezinkulumo zokuhlukanisa izibonakaliso zenkulumo ezihlanzekile kusuka kumsindo wasemuva.
Umsindo we-Impulse ngumsindo we-sceble ongalethwa ngenxa ye-Dynamic Velle effect lapho indawo yelitshe lokutholwa iphazanyiswa ukukhanya kokutholwa kohlelo lokutholwa kwe-LDV. Njengamanje, lolu hlobo lomsindo lususwa ikakhulukazi ngokuthola indawo lapho isiginali inethanga eliphakeme lamandla bese lilifaka esikhundleni senani elibikezelwe.
Ukutholwa kwezwi laseLaser Remote Voice kunethemba lesicelo emikhakheni eminingi efana nokuqondakala, ukubonwa kwemodi ehlukahlukene, ukusesha okulinganiswayo, ukwenziwa kwesilinganiso sokulinganisa, ukulungiselela imodi yokuthola, izakhi nokwakheka kohlelo lokutholwa; . . (4) Thuthukisa ukwakheka kwesistimu, futhi uphinde wenze kahle uhlelo lokutholwa ngalo

I-miniaturization, ukuthwala kanye nenqubo yokuthola ihlakaniphile.
