Piav qhia: Tus cyclic codes yog subclass ntawm cov cai tawm . Nws yog tsim los siv cov lus tawm tswv yim hloov pauv cov npe. Piav qhia: A. cyclic code tuaj yeem tsim siv lub tshuab hluav taws xob polynomial thiab thaiv cov cai tuaj yeem tsim tawm siv cov tshuab hluav taws xob.

Ib yam li ib tus tuaj yeem nug, yam khoom muaj txiaj ntsig ntawm cyclic codes yog dab tsi?

Cyclic code . Hauv coding kev tshawb xav, a cyclic chaws yog thaiv chaws , qhov kev hloov pauv ntawm txhua kab lus muab lwm lo lus uas yog rau chaws . Lawv yog cov yuam kev-kho cov lej uas muaj algebraic khoom uas yooj yim rau kev ua yuam kev pom thiab kho.

Kuj Paub, qhov zoo ntawm cov lej cyclic yog dab tsi?

  • Li no rau, loj n thiab k. yuav tsum tau siv (swb tom ntej)
  • Cyclic lis dej num yog.
  • Qhov Zoo: Nkag siab, txiav txim siab thiab ua lej yooj yim los ntawm kev hloov npe.

Kuj Paub, dab tsi yog linear block codes?

Hauv coding kev tshawb xav, a linear code yog qhov ua yuam kev-kho chaws rau leej twg tawm ua ke ntawm codewords kuj yog ib tug codeword. Cov kab lus hauv a linear block code yog thaiv ntawm cov cim uas tau encoded siv cov cim ntau dua li tus nqi qub yuav raug xa mus.

Cov cuab yeej ntawm txoj kab thaiv kab tawm yog dab tsi?

2. LUS QHIA LINEAR BLOCK CODEIn ib (n, k) linear block code : 1st feem ntawm cov khoom me me ib txwm zoo ib yam rau cov lus sib txuas kom xa mus. Qhov thib ob ntawm (n-k) cov khoom tau suav los ntawm cov ntawv me me raws li txoj cai encoding thiab hu ua parity bits.
