Turbo codes, CRC, error detection.
Turbo codes mark one of the most important
developments in coding theory. The systematic
component of a terminated recursive systematic
convolutional code used as a constituent code in turbo
codes provides a built-in cyclic redundancy check (CRC).
In this paper we show that this built-in CRC can be used
in conjunction with an external CRC to reduce the
redundancy required for error detection or enhance error
