Abstract: Phase shift values between signals received at a plurality of receiving antennas are determined to orient one or more receiving antennas of the plurality of receiving antennas during signal location. Subsequent signals are received utilizing the oriented receiving antennas. Candidate angle of arrival (AOA) values are computed based on the determined phase shift values during the signal location so as to adaptively orient the receiving antennas. Each of the candidate AOA values is iteratively selected one at a time to adaptively orient the receiving antennas. The receiving antennas may be adaptively oriented according to the computed receive signal power levels. The determined phase shift values may be rounded to nearest discrete phase shift values. In this regard, one candidate AOA value is selected for each of the receiving antennas based on the corresponding rounded phase shift values such that the receiving antennas may be adaptively oriented during the signal location.

Abstract: Methods and systems for enabling coexistence of multiple potentially interfering wireless components in a device are provided. A device may include a wireless module using a proprietary protocol and one or more modules using standardized protocols. The device further includes a coexistence arbitration module configured to arbitrate access to a shared communication medium among the wireless modules based on assertion of medium access requests by the modules and the associated priority of the asserted medium access requests. When multiple medium access requests have the same priority, precedence for access to the shared medium is determined based on additional criteria. The coexistence arbitration module may be a separate module or may be integrated into another module or distributed among the modules. The device may include a host processor for altering transmission characteristics of a module to increase the likelihood that another module can receive data within a reasonable time period.

Abstract: Aspects of a method and system for wireless local area network (WLAN) phase shifter training are presented. Aspect of the system may enable a receiving station, at which is located a plurality of receiving antennas, to estimate the relative phase at which each of the receiving antennas receives signals from a transmitting station. This process may be referred to as phase shifter training. After determining the relative phase for each of the receiving antennas, the receiving station may process received signals by phase shifting the signals received via each of the receiving antennas in accordance with the relative phase shifts determined during the phase shifter training process. Signals received via a selected one of the receiving antennas may be unshifted. The processed signals may be combined to generate a diversity reception signal.
