Receiving method and receiving apparatus with adaptive array signal processing

[0029] The present invention is described below based on examples, which do not limit the scope of the present invention but are examples of the present invention. All features and combinations thereof described in these embodiments are not essential to the invention.

[0030] Before describing the present invention in detail, its gist will be described first. Embodiments of the present invention relate to a base station apparatus that performs adaptive array signal processing on a plurality of signals received by a plurality of antennas. It is assumed that the type of base station device targeted by the present application is a base station device for a wireless local area network (LAN). The wireless LAN handled in the base station apparatus is based on a system conforming to IEEE 802.11a, a system conforming to IEEE802.11b, and a system conforming to IEEE 02.11g. In other words, the base station device can use two frequencies of 2.4GHz and 5GHz as radio frequencies. A spread
