<p>The present invention is able to decode a trellis coding modulated signal without the increase in memory capacity and circuit size even when multiple trellis decoding circuits are not used. A receiving apparatus (100) comprises: a receiving unit (101) which receives a trellis coding modified signal in which data modified in multiple trellis coding modifiers is multiplied; an equivalent circuit (105) which arranges multiplied data in received trellis coding modified signal in order to continue modified data in each trellis coding modifier several times in modified sequence; a trellis decoding circuit (108) which trellis-decodes arranged data; and a data rearrangement circuit (111) which re-arranges decoded data in order to perform multiplied order with the trellis coding modified signal.
