RT Journal Article SR Electronic A1 Franekova, Maria T1 Mathematical Apparatus for Error Probability Determination of Block Code Decoders JF Communications - Scientific Letters of the University of Zilina YR 2001 VO 3 IS 4 SP 59 OP 64 DO 10.26552/com.C.2001.4.59-64 UL https://komunikacie.uniza.sk/artkey/csl-200104-0010.php AB This paper deals with safety - related communication in closed transmission systems when block systematic (n, k) safety codes are used. The mathematical apparatus for calculation of probability of undetected sequence error is described for codes, with known and unknown weight structure. The numerical results are valid for a Symmetric Binary Channel when the occurrence of independent errors is assumed.
