Patent ID: 8340226

Claim:
A multi-antenna receiving apparatus that receives a plurality of modulated signals transmitted from a plurality of antennas at the same time, using a plurality of antennas, and reconstructs a data sequence associated with each modulated signal from the received signal, the multi-antenna receiving apparatus comprising: a decision section that identifies the modulated signals based on signal point distances between a plurality of candidate signal points of a signal, in said signal the plurality of modulated signals being multiplexed, and a signal point of the received signal; a decoding section that obtains digital data of the modulated signals using a decision result obtained in the decision section; and a signal point canceling section that calculates the candidate signal points by using, recursively, all combinations of bit sequences having at least one bit as a negated value and a plurality of digital data, in a plurality of digital data that form the modulated signals not including a modulated signal of interest, obtained in the decoding section.
