Title: DIRECTIONAL PATTERN-DECISION METHOD
Abstract:
A plurality of directional patterns are grouped such that patterns with high mutual correlation are in the same groups and patterns with low mutual correlation are in different groups. The grouped patterns are stored in a directional pattern memory (104m). One directional pattern from each group is selected from the directional pattern memory (104m). Each time a variable-direction antenna element (102-1 to 102-3) is set with selected directional patterns, one of the selected directional patterns is decided upon, according to the quality of a received signal. The variable-direction antenna element (102-1 to 102-3) is then set with the directional pattern that was decided upon.
