Abstract
An apparatus for generating a detected punctured position in punctured convolutional codes. A delay line circuit has a plurality of delay elements connected in series, storing a finite sequence of an input bit stream. A logic gate circuit, coupled to outputs of a part of the delay elements of the delay line circuit in accordance with a parity check polynomial, performs a logic operation to output a number stream. The number stream is accumulated for possible punctured positions and the one of the possible punctured positions with a minimal accumulated number is selected and determined as the detected punctured position.
