Angle of arrival and/or range estimation within a wireless communication device

Angle of arrival and/or range estimation within a wireless communication device. Appropriate processing of communications received by a wireless communication device is performed to determine the angle of arrival of the communication (e.g., with respect to some coordinate basis of the wireless communication device). Also, appropriate processing of the communications may be performed in accordance with range estimation as performed by the wireless communication device to determine the distance between the transmitting and receiving wireless communication devices. There are two separate modes of packet processing operations that may be performed: (1) when contents of the received packet are known, and (2) when contents of the received packet are unknown. The wireless communication device includes a number of antenna, and a switching mechanism switches from among the various antennae capitalizing on the spatial diversity of the antennae to generate a multi-antenna signal.

20170090012 · 2017-03-30 ·

An enhanced radar detector in one example displays a source direction of one more detected signals simultaneously with a frequency band of the detected signal. In another embodiment, a method detects a location of a false alert source to suppress alerts emanating from the location. A geographic location of a first mid-ship point of a detected radar signal in a vehicle traveling in a first direction are identified/recorded. The geographic location of a second mid-ship point of a detected signal is also identified/recorded in a vehicle traveling in a second different direction. The recorded geographic locations/directions of travel are uploaded to a host server, or evaluated within the radar detector, to identify a false source and mark a false source at an intersection of the first and second midlines. The marked false source location can be used in a detector and/or downloaded to multiple detectors via a social network.
