ADAPTIVE POINTING FOR DIRECTIONAL ANTENNAS

摘要

A directional antenna is pointed based on a ranking process. The ranking process of choice uses both ES/NO and Pilot Power parameters as measured from a pilot signal for best overall system performance in the forward and reverse links. Using this pointing and ranking process enables adaptive pointing of the directional antenna in interference and multi-path driven environments. The pointing and ranking process may be used to select the "best" pointing angle for communicating with a given base station or for selecting the given base station. The process may include fine tuning techniques for use in different environments. The fine tuning may include the use of weights related to the operating environment or directivity of the directional antenna.
