SMALL DISTANCE CODES FOR HEADER ERROR DETECTION IN ATM NETWORKS
Abstrak: On transmission links
with relatively low bit error rates, error detection codes that have been widely
used have dmin = 3.
These codes may
be unneccesarily powerful
for fibre links because
they require an
excessive number of
redundant parity check
bits. For the purpose of
error detection in ATM networks
using optical fibre
links, some high-rate, small distance
codes with dmin = 2
may be appropiate.
These codes, called
Small Distance Codes, can
be used to
detect all single-error
patterns and a
large fraction of double errors and other patterns. This
paper describes the application of small distance codes for
error detection in the ATM cell header. Performances analysis are given
and compared to the 8-bit CRC recommended by ITU-T. Three alternatives are
examined and analysed. The results are displayed and compared to the standard
8-bit CRC and to 10-bit CRC for ATM network as well.
