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.
Claims22
A circuit, comprising:
- a memory storing instructions;
- a receive chain;
- and
- a processor coupled to the memory and to the receive chain, the processor configured to execute the instructions to:
- receive, via the receive chain using a first antenna, a first portion of a preamble of a wireless transmission;
- receive, via the receive chain using a second antenna, a second portion of the preamble of the wireless transmission;
- and
- determine an angle of arrival of the wireless transmission based on the first portion and the second portion of the preamble of the wireless transmission.
A method comprising:
- receiving, with a first antenna, a first portion of preamble or a body of a wireless transmission;
- determining when a second portion of the preamble or the body of the wireless transmission is expected to be received;
- receiving, with a second antenna, the second portion of the preamble or the body of the wireless transmission;
- and
- determining an angle of arrival of the wireless transmission based on the first portion and the second portion of the preamble or the body of the wireless transmission.
