Adaptive antenna diversity receiver

摘要

The receiver includes a correction circuit (13) which receives antenna signals from at least two spaced-apart antennas (11,12). A corrected signal is synthesised as a weighted combination of the antenna signals. A diversity selecting circuit (14) receives the antenna signals and generates a diversity signal which corresponds to a selection of a best one of the antenna signals according to a diversity criterion. A signal quality monitor circuit (17) is coupled to the correction circuit and the diversity selecting circuit for measuring a predetermined quality of the corrected signal and the diversity signal. A selection circuit (18) outputs either the corrected signal or the diversity signal in response to the measured predetermined quality.
