WIRELESS RECEIVING APPARATUS, WIRELESS TRANSMITTING APPARATUS, AND INTERFERENCE SIGNAL REMOVING METHOD |
摘要 |
A wireless receiving apparatus capable of efficiently removing interference signals in a multicarrier communication. In a mobile station (200) incorporating this wireless receiving apparatus, a selecting part (205) 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 (207) 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 (208) performs an MMSE processing to determine a weight (W) from both a P-vector received from a channel estimating part (206) and the inverse matrix of the R-matrix received from the correlation value calculating part (207). Multipliers (209-1 to 209-N) multiply each of the symbols selected by the selecting part (205) by the weight determined by the MMSE processing part (208).
A combining part (210) combines the symbols as multiplied by the weight.
