ABSTRACT:
The present invention relates to a decoder for tail-biting convolution codes and a method thereof. The decoder receives an encoding bit sequence in a convolutional encoding method from a channel, generates an expanded encoding bit sequence, Viterbi decodes the expanded encoding bit sequence, and generates decoded data. In addition, the decoder selects a central bit sequence of the decoded data, rearranges the central bit sequence, and generates final decoded data. Accordingly, the decoder has a simplified configuration for decoding the bit sequence encoded in the tail biting convolutional encoding method, and the decoder also decodes a bit sequence encoded in a zero-tail convolutional encoding method.
