Provided is a receiving apparatus that includes a receiving unit which receives a trellis-coded modulation signal in which data items modulated by a plurality of trellis-coded modulators have been multiplexed; a data processing unit which arranges the data items multiplexed in the trellis-coded modulation signal received by the receiving unit so that a given number of data items modulated by one of the trellis-coded modulators are arranged consecutively in first order in which the data items modulated by one of the trellis-coded modulators have been modulated as arrangement processing and the arrangement processing is repeated in remaining trellis-coded modulators; a trellis decoding unit which performs trellis decoding of the data items arranged by the data processing unit, thereby producing decoded data items; and a data rearranging unit which rearranges the decoded data items in second order in which the decoded data items have been multiplexed in the trellis-coded modulation signal.
