ABSTRACT:
In a method and apparatus for convolutionally encoding a finite length digital data bit stream, the information samples arriving at the output of each encoder shift register are fed back to its input to simulate an infinite periodic data bit stream. Recirculation of the received information and parity symbols is also used for decoding.
