摘要
PURPOSE: An apparatus improves the coding gain by performing a partial overlap quantization modulation applying a convolution code in a communication system. CONSTITUTION: An apparatus comprises: an information separating part(1) separating information sequence into a fixed bits; an encoding part(2) encoding some of the fixed bits separated in the information separating part; a buffering/dummy signal outputting part(3) buffering the significant bit value according to the fixed value separated in the information separating part or outputting by mixing a dummy signal; and a mapping part(4) mapping the signal of the encoding part, the information separating part and the buffering/dummy signal outputting part.
