<P>PROBLEM TO BE SOLVED: To provide a method and apparatus that performs high-speed iterative decoding of a code obtained by two or more different convolutional coding schemes. Ž<P>SOLUTION: The method has processes: to decide whether the number of decoding iteration is equal to a predetermined maximum iteration number or not; to decide whether a packet storage element combined with the input of an iterative decoder is within a predetermined proportion of a storage capacity of a packet storage element or not; to decide whether the number of decoding iteration is equal to a predetermined minimum iteration number or not; to decide whether an error detection measurement is satisfactory or not regarding at least one foregoing packet, and to terminate the iterative decoding processing for the packet (1) when the number of decoding iteration is equal to a predetermined maximum iteration number, (2) when the packet storage element is within a predetermined proportion of the storage capacity of the packet storage element, or (3) when the number of decoding iteration is equal to a predetermined minimum iteration number and the error detection measurement is satisfactory regarding at least one foregoing packet.
