Reception apparatus and reception method for improving MIMO transmission

摘要

The present invention provides a reception apparatus and reception method that reduce the amount of operation processing, reduce the processing delay and allow high signal separation performance. The reception method of the present invention is characterized by receiving signals including a plurality of codewords transmitted by a plurality of streams and performing maximum likelihood detection-based signal separation in the same codeword in the received signals while performing continuous interference canceller-based signal separation between different codewords.

主权项

1. A reception apparatus comprising:
a reception section configured to receive signals including a plurality of codewords transmitted by a plurality of streams; and a signal separation section configured to separate the codewords from the received signals, wherein the signal separation section comprises: a maximum likelihood detection signal separation section configured to perform maximum likelihood detection-based signal separation in a same codeword; and a continuous interference canceller signal separation section configured to perform continuous interference canceller-based signal separation between different codewords; wherein, when, after maximum likelihood detection-based signal separation is performed with respect to a certain codeword and there is no frame error after channel decoding, the signal separation section performs continuous-interference canceller-based signal separation using a hard decision decoding result, and, after that, performs maximum likelihood detection-based signal separation with respect to another codeword.
