Abstract
An embodiment encoder device for encoding an information word c=[c, c, . . . , c] having K information bits, c, includes an encoder for a tail biting convolutional code having a constraint length, L, where K<L−1; the encoder being configured to receive the K information bits; and encode the K information bits so as to provide an encoded code word. An embodiment decoder device for determining an information word c=[c, c, . . . , c], having K information bits, c, includes a decoder for a tail biting convolutional code having a constraint length, L, where K<L−1; the decoder being configured to: receive an input sequence; compute at least one reliability parameter based on the received input sequence; and determine an information word c based on the at least one reliability parameter.
