Abstract
Techniques for determining an angle-of-arrival of a wireless transmission are provided, including receiving, with a first antenna, at least a first portion of a wireless transmission, determining when a second portion of the wireless transmission will be received, switching to the second antenna to receive the second portion of the wireless transmission, determining an angle of arrival of the wireless transmission based on the first portion and the second portion of the wireless transmission, and outputting the angle of arrival of the wireless transmission.
Claims20
A wireless device comprising:
- a first switch comprising a first terminal coupled to a first antenna terminal that is configured to be coupled to a first antenna, a second terminal coupled to a second antenna terminal that is configured to be coupled to a second antenna, and a third terminal;
- a second switch comprising a first terminal coupled to the third terminal of the first switch, a second terminal, and a third terminal;
- a transmitter chain coupled to the second terminal of the second switch;
- a receiver chain coupled to the third terminal of the second switch, wherein the receiver chain is configured to receive a first portion of a wireless transmission via the first antenna, and a second portion of the wireless transmission via the second antenna;
- and
- a processor configured to:
- determine an angle of arrival of the wireless transmission based on the first and second portions, and
- output the angle of arrival.
A wireless device comprising:
- a first antenna terminal configured to be coupled to a first antenna;
- a second antenna terminal configured to be coupled to a second antenna;
- a receiver chain coupled to the first and second antenna terminals, wherein the receiver chain is configured to receive a first portion of a wireless transmission via the first antenna, and a second portion of the wireless transmission via the second antenna;
- and
- a processor configured to:
- determine an angle of arrival of the wireless transmission based on the first and second portions, and
- output the angle of arrival, wherein the wireless transmission is addressed to another wireless device.
A wireless device comprising:
- a first antenna terminal configured to be coupled to a first antenna;
- a second antenna terminal configured to be coupled to a second antenna;
- a receiver chain coupled to the first and second antenna terminals, wherein the receiver chain is configured to receive a first portion of a wireless transmission via the first antenna, and a second portion of the wireless transmission via the second antenna;
- and
- a processor configured to:
- determine an angle of arrival of the wireless transmission based on the first and second portions, and
- output the angle of arrival, wherein the wireless transmission is addressed to another wireless device, wherein the receiver chain is configured to receive, after receiving the second portion via the second antenna, a remainder of the wireless transmission via the first antenna.
