Abstract
Techniques to select an antenna from a plurality of antennae used for wireless communications are described. A first embodiment of the techniques is a method to select an antenna from a plurality of antennae. The method includes monitoring at least one antenna during a fraction of at least one preamble period of a frame to derive at least one quality indicator corresponding to the antenna; storing the quality indicator derived from monitoring the antenna during the fraction of the preamble period of a frame; and selectively switching to a selected antenna after a number of frames, based on the quality indicator. A second embodiment is another method to select an antenna from a plurality of antennae. These embodiments can be applied in several wireless communication applications using multiple antennae.
