Umfanekiso 2-2. IViterbi Decoder Architecture
I-Viterbi Decoder ineebhloko ezintathu zangaphakathi ezichazwe ngolu hlobo lulandelayo:
- IYunithi yeMetric yeSebe (BMU): I-BMU ibala umahluko phakathi kophawu olufunyenweyo kunye nayo yonke imiqondiso enokubakho yokuhanjiswa, isebenzisa iimetrics ezifana neHaming distance yedatha yokubini okanye umgama we-Euclidean kwizikim zokumodareyitha eziphambili. Olu balo luvavanya ukufana phakathi kweempawu ezifunyenweyo kunye nezinokuthi zidluliselwe. I-BMU iqhuba ezi metrics kwisimboli nganye efunyenweyo okanye isuntswana kwaye igqithisele iziphumo kwiYunithi yeMetriki yeNdlela.
- Iyunithi yeMetric yeNdlela (PMU): I-PMU ekwaziwa ngokuba yiYunithi yoFakela-Thelekisa-Khetha (ACS), ihlaziya iimethrikhi zendlela ngokucubungula iimethrikhi zesebe ukusuka kwi-BMU. Igcina umkhondo weyona metric eyongezelekayo yendlela yelizwe ngalinye kwidayagram yetrellis (umboniso womzobo wotshintsho olunokwenzeka lukarhulumente). I-PMU yongeza i-metric yesebe elitsha kwindlela yangoku yemetric yelizwe ngalinye, ithelekisa zonke iindlela ezikhokelela kweso sixeko, kwaye ikhethe leyo eneyona metric isezantsi, ibonisa eyona ndlela inokwenzeka. Le nkqubo yokhetho iqhutywa kwinqanaba ngalinyetage ye trellis, ekhokelela kwingqokelela yeendlela ezinokwenzeka, ezaziwa ngokuba ziindlela zamaxhoba, kwiphondo ngalinye.
- IYunithi yokuLandela umva (TBU): I-TBU inoxanduva lokuchonga olona landelelwano lunokwenzeka lwamazwe, kulandela ukusetyenzwa kweesimboli ezifunyenwe yi-PMU. Ifezekisa oku ngokulanda kwakhona i-trellis ukusuka kwimeko yokugqibela ngeyona metric yendlela isezantsi. I-TBU iqalisa ukusuka ekupheleni kwesakhiwo se-trellis kwaye ilandelela emva kwiindledlana zexhoba isebenzisa izalathisi okanye iimbekiselo, ukumisela olona landelelwano lunokwenzeka losasazo. Ubude bomkhondo we-traceback bumiselwa bubude obubambekayo bekhowudi ye-convolution, echaphazela zombini ukuhla kwekhowudi kunye nobunzima. Ekugqibezeleni inkqubo yokulandelela umva, idatha ekhutshiweyo inikezelwa njengemveliso, ngokuqhelekileyo kunye namasuntswana omsila ahlonyelweyo asusiweyo, afakwe ekuqaleni ukucima i-encoder convolutional.
I-Viterbi Decoder isebenzisa ezi yunithi zintathu ukuchaneka ngokuchanekileyo isignali efunyenweyo kwidatha yokuqala edluliselweyo, ngokulungisa naziphi na iimpazamo ezinokuthi zenzeke ngexesha lokudluliselwa.
Eyaziwayo ngokusebenza kwayo, i-algorithm ye-Viterbi yindlela eqhelekileyo yokuguqula iikhowudi ze-convolutional ngaphakathi kweenkqubo zonxibelelwano.

Microchip Devices Code Protection Feature
Qaphela ezi nkcukacha zilandelayo zenqaku lokhuseleko lwekhowudi kwiimveliso zeMicrochip:
- Iimveliso zeMicrochip ziyahlangabezana nemigaqo equlethwe kwiMicrochip Data Sheet yazo.
- IMicrochip ikholelwa ukuba usapho lwayo lweemveliso lukhuselekile xa lusetyenziswa ngendlela ecetywayo, ngokwemigaqo yokusebenza, naphantsi kweemeko eziqhelekileyo.
- Ixabiso leMicrochip kwaye likhusela ngokungqongqo amalungelo epropathi enomgangatho ophezulu wokuqonda. Iinzame zokwaphula ikhowudi yokukhusela iimpawu zeMicrochip zithintelwe ngokungqongqo kwaye zinokwaphula umthetho weDigital Millennium Copyright Act.
- Ayikho i-Microchip okanye nawuphi na umenzi we-semiconductor onokuqinisekisa ukhuseleko lwekhowudi yayo. Ukukhuselwa kwekhowudi akuthethi ukuba siqinisekisa ukuba imveliso "ayinakwaphulwa". Ukhuseleko lwekhowudi luhlala luvela. I-Microchip izinikele ekuphuculeni ngokuqhubekayo iimpawu zokukhusela ikhowudi kwiimveliso zethu.
Isaziso soMthetho
Olu papasho kunye nolwazi olulapha lunokusetyenziswa kuphela ngeemveliso zeMicrochip, kubandakanywa ukuyila, ukuvavanya, kunye nokudibanisa iimveliso zeMicrochip kunye nesicelo sakho. Ukusetyenziswa kolu lwazi
ngayo nayiphi na enye indlela yophula le migaqo. Ulwazi malunga nosetyenziso lwesixhobo lunikezelwa kuphela ukulungiselela wena kwaye lunokuthi luthathelwe indawo luhlaziyo. Luxanduva lwakho ukuqinisekisa ukuba isicelo sakho siyadibana neenkcukacha zakho. Qhagamshelana neofisi yakho yentengiso yeMicrochip yengingqi ngenkxaso eyongezelelweyo okanye, ufumane inkxaso eyongezelelweyo kwi www.microchip.com/en-us/support/design-help/client-support-services.
