Abstract
An improved smart antenna reception method and devices are provided that determine when to select a new antenna configuration in a multiple antenna configuration system. One embodiment attempts to eliminate unneeded configuration searching. Unneeded configuration searching can degrade overall signal quality and system performance. Configuration changing can be minimized by determining that a signal quality received from a first antenna configuration is below a threshold and changing antenna configuration. After changing antenna configuration, if the signal quality received from the second antenna configuration is lower than the signal quality received from the first antenna configuration the threshold can be lowered. By lowering the threshold, the probability of additional configuration changing can be reduced.
