Base station device and radio receiving method

摘要

Direction of arrival estimation sections 111 to 113 carry out direction of arrival estimation on communication terminals 120 to 122. Group generation section 115 generates a group composed of communication terminals with similar directions of arrival viewed from the base station apparatus. Group representative station selection section 116 selects one or several communication terminals from the group. Adaptive signal processing section 117 carries out adaptive signal processing on the communication terminal selected from the group and generates a reception weight for each group. This reception weight is used as the reception weight for all communication terminals that belong to each group and multiplied on the reception signal by multipliers 118 and 119. These multiplication results obtained are used for interference canceller processing and normal interference canceller processing is carried out on the communication terminals in the group.
