Abstract:
1. A method comprising: (a) receiving a radio signal on a plurality of antenna elements; (b) computing a signal quality metric for the signal received on each of the antenna elements; (c) determining a difference value between the signal quality metric for a currently selected antenna element and the signal quality metric for each of the other antenna elements; (d) finding the minimum difference value; (e) determining (1) if a dwell value is greater than a multiple of the minimum difference value and (2) if the signal quality metric computed for the currently selected antenna element is less than a threshold value; and (f) if either or both of (1) or (2) in step (e) is true, then switching from the currently selected element to one of the other antenna elements for supplying the radio signal to a receiver and repeating steps (b) through (e).
