TRANSMISSION APPARATUS AND TRANSMISSION METHOD

摘要

A wireless receiving apparatus capable of efficiently removing interference signals in a multicarrier communication. In a mobile station incorporating this wireless receiving apparatus, a selecting part selects a plurality of the same symbols in accordance with a mapping pattern established at the time of generating OFDM symbols in a base station. A correlation value calculating part determines correlation values between the subcarriers of the same symbols to generate an R-matrix, and further determines an inverse matrix of the R-matrix. An MMSE processing part performs an MMSE processing to determine a weight from both a P-vector received from a channel estimating part and the inverse matrix of the R-matrix received from the correlation value calculating part. Multipliers multiply each of the symbols selected by the selecting part by the weight determined by the MMSE processing part. A combining part combines the symbols as multiplied by the weight.
