Abstract
An apparatus and method are disclosed for achieving receiver diversity. A wireless unit includes a plurality of antennas, an antenna selector to select one or more antennas from the plurality of antennas, a processor with input data from an inertial sensor for monitoring the orientation of the wireless unit. Based on the input data, the processor commands the antenna selector to select one or more antennas. In some embodiments, the processor is a diversity processor. Based on the input data from the inertial sensor, the diversity processor computes the combination of the received signals. In another aspect, the wireless unit further includes a baseband processor to process the output of the diversity processor for a particular unit application.
