Abstract: A directional pattern table memory stores combined directional pattern groups in each of which combined directional patterns are ordered by different predetermined priority according to a different radio propagation environment. A controller computes a communication performance expected value based on RSSIs for when an initial combined directional pattern is set on steerable antenna apparatuses; selects one combined directional pattern group based on relative strengths of RSSIs; and according to the priority, sequentially sets combined directional patterns of the selected one combined directional pattern group, on the steerable antenna apparatuses, computes a communication performance value based on a PHY rate and a PER at each of sequential settings, and performs communication using a combined directional pattern with a communication performance value that first exceeds the communication performance expected value.

Abstract: Aspects of a method and system for using a wireless local area network (WLAN) phase shifter for smart antenna beam steering are presented. Aspects of the system may enable determination of an angle of arrival (AOA) for signals received at a receiving station in a wireless network. Based on the AOA value, the receiving station may enable orientation of antenna in a smart antenna system. In a switched beam smart antenna system, antenna element(s) may be selected, which are most closely oriented toward the AOA. In an adaptive array smart antenna system, antenna beam may be steered, or reoriented, based on the AOA.

Abstract: In an adaptive array antenna receiving apparatus, signal to interference ratio (SIR) measuring units are provided in signal processing units, respectively. The SIR measuring units measure signal to interference ratios of existing fingers to supply the measured results for an antenna weight succession processing unit. The antenna weight succession processing unit selects one of the existing fingers on the basis of the measured results. The antenna weight succession processing unit extracts antenna weights from one of the signal processing units that corresponds to the selected finger. The antenna weight succession processing unit supplies the extracted antenna weights to a newly assigned finger or one of the existing fingers that path timing is greatly changed.
