Sawubona Bafundi, Kulesi sihloko sizofunda ukuthi yini Ukulawula Amaphutha kanye nokuhlelwa kokulawula amaphutha.
Enqubweni yokudluliswa kwedatha, ngenxa yethonya lomsindo esiteshini, i-waveform yesiginali ingase ihlanekezelwe lapho idluliselwa kumamukeli, okuholela kumaphutha olwazi. Ukuze uhlangabezane nezidingo ezilindelekile zalawa maphutha, ukulawulwa kwamaphutha kuyadingeka. Umgomo wokulawula amaphutha ukuthi ngemva kokuthi amabhithi e-K olwazi edlulisiwe, kukhona amabhithi angama-R wamabhithi angasadingeki enanini lesitoko. Ulwazi olutholwe umamukeli lusebenzisa i-algorithm ehlanganisiwe, futhi umphumela uqhathaniswa nomphumela womthumeli. iphutha. Uma umamukeli azi ukuthi kunephutha, kodwa engazi ukuthi iphutha liyini, bese ecela ukudluliselwa kumthumeli, leli su libizwa ngokuthi ukutholwa kwephutha; uma umamukeli azi ukuthi kunephutha futhi azi ukuthi iphutha liyini, leli su libizelwa ukulungisa iphutha.
(2) Ukuhlelwa kokulawula iphutha
Kunezinhlobo ezimbili zokulawula amaphutha: amaphutha amancane namaphutha ozimele. Iphutha elincane liyiphutha elincane, u-1 uba ngu-0, u-0 uba ngu-1; kunamaphutha amathathu ozimele okungenzeka: ukulahlekelwa, ukuphindaphinda, nokuphuma kwe-oda. Uma kunephutha elihlobene, ngakho-ke sidinga ukucela isisombululo kusuka kusendlalelo sesixhumanisi sedatha kuya kuseva enikezwe isendlalelo senethiwekhi. Isendlalelo sesixhumanisi sedatha sinikeza imisebenzi emithathu eyisisekelo kusendlalelo senethiwekhi:
1. Akukho ukuqinisekiswa futhi akukho sevisi yokuxhuma.
2. Qinisekisa ukuthi ayikho isevisi yokuxhuma.
3. Amasevisi agxile ekuxhumaneni aqinisekisiwe.
Okungenhla incazelo yolwazi "Yokulawula Iphutha" elethwa i-Shenzhen HDV photoelectric Technology Co., Ltd. Imikhiqizo yokuxhumana ekhiqizwe ikhava yenkampani: Izigaba zamamojula: amamojula we-fiber optical, Amamojula we-Ethernet, amamojula we-fiber optical transceiver, amamojula okufinyelela kwefiber optical, Amamojula we-SSFP optical, futhiImicu ye-Optical SFP, njll.
I-ONUisigaba: EPON ONU, AC ONU, i-fiber optical ONU, I-CATV ONU, I-GPON ONU, XPON ONU, njll.
OLTisigaba: Ukushintsha kwe-OLT, I-GPON OLT, I-EPON OLT, ukuxhumanaOLT, njll.
Imikhiqizo yemojula engenhla ingahlinzeka ngosekelo lwezimo zenethiwekhi ezahlukahlukene. Ithimba le-R&D elichwepheshile neliqinile lingasiza amakhasimende anezinkinga zobuchwepheshe, futhi ithimba lebhizinisi elicabangayo nelichwepheshile lingasiza amakhasimende ukuthi athole amasevisi ekhwalithi ephezulu ngesikhathi sokubonisana kwangaphambilini nomsebenzi wangemuva kokukhiqiza. Siyakwamukela kuXhumana nathi nganoma yiluphi uhlobo lombuzo.
