Patent Images
1. A method, comprising:
- sensing, using one or more sensors in a device, information related to a state and/or alignment of a device;
configuring direction of arrival estimation functionality in the based on the information sensed by the one or more sensors; and
determining a direction of arrival estimate of a received signal in the device, wherein at least one sensed condition related to the received signal is used to alter the behavior of the direction of arrival estimation functionality.

Abstract
A system for enhancing the performance of a wireless communication device (WCD) while executing a direction of arrival (DoA) estimation. The performance may be improved through device management, and may include the collection of information from one or more sensors installed within the WCD. The sensor information may initially be used to determine an appropriate configuration for the device. Further, the sensor information may also be used to affect the behavior of the device while performing the DoA estimation.
