Abstract:
1. A receiving apparatus comprising: a plurality of receiving antennas; a first decoder section that decodes a data sequence received in the receiving antennas, and outputs a first decoded signal; a first conversion section that, according to known rearrangement rules, converts an order of writing or reading channel estimation information generated from the data sequence; a first storage section into which and from which the channel estimation information is written and read, in the converted order; a second conversion section that, according to the known rearrangement rules, converts an order of writing or reading the data sequence; a second storage section into which and from which the data sequence is written and read, in the converted order; a re-modulation section that, based on the channel estimation information, re-modulates the first decoded signal and generates re-modulated data; a cancellation section that extracts the channel estimation information from the first storage section and the data sequence from the second storage section, in the converted order, and generates a signal stream from which an interference signal in the data sequence is canceled, using the channel estimation information, the first decoded signal and the re-modulated data; and a second decoder section that, based on the signal stream, performs decoding and outputs a second decoded signal.
