A method and system for antenna selection diversity with dynamic gain
control. A receiver selects a starting antenna and dwells on it until an
incoming signal is detected. An AGC is applied on the received signal and
an estimate of the received power is determined for the starting antenna.
The receiver may dwell on other antennas if the signal in the first
antenna is not strong enough for signal processing. The gain of an
antenna may be set by the gain and power levels of the previously
dwelled-on antennas and/or by a power coupling factor that exists between
the antennas in an antenna switch. The receiver switches through the
remaining antennas as long as necessary to select at least one of the
antennas for signal processing. Dynamically adjusting the gain of
antennas in a diversity system provides a more accurate and efficient
antenna selection scheme.
