Abstract
A találmány tárgya egyrészt kódoló berendezés bináris forrásjel (S)adatbit folyamának bináris csatornajel (C) adatbit folyamra valókódolásához, ahol a forrásjel bitfolyamát n bitből álló forrásszavakraosztják. A kódoló berendezés tartalmaz egy átalakító eszközt (LC), amelyalkalmas a forrásszavak megfelelő m bitből álló csatornaszavakkáalakítására. Az átalakító eszköz (LC) alkalmas arra, hogy egymástkövető n bitből álló forrásszavakat megfelelő egymást követő m bitbőlálló csatornaszavakká alakítsa, úgy, hogy az n bites forrásszavakmindegyik blokkja az átalakítás során alapvetően megőrzi a paritását,és hogy m n 1; célszerűen m = n + l. A berendezés alkalmas aforrásjelben nyolcbites 00010001" bitsorozat tizenkét bites100010010010" bitsorozattá alakítására és a nyolcbites 10010001"bitsorozat tizenkét bites 100010010010" bitsorozattá alakítására, hogyaz ismételt minimális átviteli futamidőt korlátozzák a csatornajelben.Más nyolcbites sorozatokat meghatározott kódolással alakítanak áttizenkét bites bitsorozatokká, hogy a csatornajel k-korlátozóját 7-rekorlátozzák. A találmány másrészt dekódoló berendezés, amely a kódolóberendezéssel kapott csatornajel dekódolására szolgál. Ó
