Iyi inotevera nhamba inoratidza iyo Viterbi Decoder architecture.
Mufananidzo 2-2. Viterbi Decoder Architecture
Iyo Viterbi Decoder ine matatu emukati mabhururu ayo anotsanangurwa seizvi:
- Bazi Metric Unit (BMU): Iyo BMU inoverenga mutsauko pakati pechiratidzo chakagamuchirwa uye ese anogona kutapurirana masaini, uchishandisa metrics akadai seHamming kureba kwebhinari data kana Euclidean chinhambwe chepamberi modulation schemes. Iyi kuverenga inoongorora kufanana pakati pezvakagamuchirwa uye zvinogoneka zvinofambiswa zviratidzo. Iyo BMU inobata aya metrics kune yega yega inogamuchirwa chiratidzo kana bhiti uye inoendesa mhedzisiro kuPath Metric Unit.
- Nzira Metric Unit (PMU): Iyo PMU iyo inozivikanwawo seye Add-Compare-Sarudza (ACS) unit, inogadziridza nzira metrics nekugadzirisa bazi metrics kubva kuBMU. Iyo inochengeta yakanakisa nzira yekuwedzera metric yedunhu rega rega mune trellis dhayagiramu (inomiririra inomiririra yezvinogoneka shanduko yenyika). Iyo PMU inowedzera iyo itsva metric yebazi kune yazvino nzira metric yedunhu rega rega, inoenzanisa nzira dzese dzinotungamira kune iyo nyika, uye inosarudza iyo ine yakaderera metric, ichiratidza nzira inogoneka. Iyi sarudzo inoitwa pane imwe neimwe stage ye trellis, zvichikonzera muunganidzwa wenzira dzinonyanya kuitika, dzinozivikanwa senzira dzekupona, dzedunhu rega rega.
- Traceback Unit (TBU): Iyo TBU ine basa rekuona iyo yakanyanya kutevedzana yenyika, zvichitevera kugadziriswa kwezviratidzo zvakagamuchirwa nePMU. Inoita izvi nekudzoreredza trellis kubva kune yekupedzisira nyika ine yakaderera nzira metric. Iyo TBU inotanga kubva kumagumo eiyo trellis chimiro uye inoteedzera kumashure kuburikidza neakapona nzira uchishandisa anonongedzera kana mareferensi, kuona iyo inonyanya kufambisa inoteedzana. Hurefu hweiyo traceback inotarwa nehurefu hwekumanikidza kwekodhi yekuchinja, zvichikanganisa zvese decoding latency uye kuoma. Paunenge wapedza iyo traceback process, iyo decoded data inounzwa sekubuda, kazhinji neyakaiswa muswe mabhiti akabviswa, ayo akatanga aisanganisirwa kubvisa convolutional encoder.
Iyo Viterbi Decoder inoshandisa aya matatu mayuniti kunyatso decode yakagamuchirwa chiratidzo mune yepakutanga yakatumirwa data, nekugadzirisa chero zvikanganiso zvingave zvakaitika panguva yekufambisa.
Inozivikanwa nekugona kwayo, iyo Viterbi algorithm ndiyo yakajairwa nzira yekudhirodha convolutional makodhi mukati mekutaurirana masisitimu.
