Title:
MEASURING ANGLE OF ARRIVAL ON A CONSTANT AND/OR PRE-KNOWN PART OF A BLE PACKET
Document Type and Number:
WIPO Patent Application WO/2020/013275
Kind Code:
A1
Abstract:
A system and method are disclosed and include receiving a wireless signal. The method includes generating a first and second set of digital data that are representative of the wireless signal. The method includes obtaining a first and second sample that is representative of a cosine and sine component, respectively, of a pre-known portion of the first set. The method includes obtaining a third and fourth sample that is representative of a cosine and sine component, respectively, of a pre-known portion of the second set. The method includes determining a first phase angle value based on an amplitude of the first and second samples and a second phase angle based on an amplitude of the third and fourth samples. The method includes determining an angle of arrival based on a difference between the first and second phase angle values.
