摘要：Methods and apparatus for selecting one or more suitable antennas for useduring power-up/initial acquisition and out of service modes are disclosed. In someexamples, initial system acquisition may be performed for a particular receive circuitutilizing a selected one of a first antenna or a second antenna, based on a channelcharacteristic, such as an automatic gain control (AGC) value corresponding to a receivedsignal energy utilizing either of the antennas. In another example, initial systemacquisition utilizing either a receive diversity determination algorithm or an antennaswitching determination algorithm may be performed based on a channel characteristic,such as an AGC value corresponding to a received signal energy utilizing one of theantennas coupled to one of the receive circuits.
