APPARATUS AND METHOD FOR TAIL BITING CONVOLUTIONAL CODING

摘要

PURPOSE: A tail biting convolution encoding device and a method thereof are provided to execute a tail biting convolution encoding by reflecting a result that an initial preset bit is encoded on the result that information bit sequence is encoded. CONSTITUTION: A buffer(100) stores a bit sequence as much as the initial L bit of the n-number of information bit sequence. An encoder(200) executes an encoding process when data is inputted to the buffer. The encoder stores the convolution-coded encoded bit sequence to a storage part(300) by convolution-encoding the n-number of information bit sequence consisting of inputted data block. The encoder encodes to the final bit of the data block. The encoder successively convolution-encodes the initial L bit saved in the buffer from the first bit. The encoder outputs the bit sequence which is tail biting convolution-encoded by arranging the convolution-encoded bit in the location of firstly encoded bit sequence among encoded bit sequence.
