Abstract: A receiver for receiving a radio signal carrying digitally-encoded data has a plurality of diversity antennas, respectively coupled to inputs of a selector. A received signal selected by the selector is equalized by an adaptive equalizer and then demodulated to recover data, when possible. A quality metric dependent on the quality of the recovered data is generated. A switch controller responsive to the quality metric controls the selector. After the controller controls the selector to select a new antenna, it monitors the quality metric as the adaptive equalizer retrains and, if the quality metric does not exceed a predetermined threshold before a predetermined forward guard time expires, the controller causes the selector to select another antenna. The switch controller may also receive a signal level signal dependent on the level of the received signal.
