Title:
GPS ANGLE-OF-ARRIVAL SELECTION SYSTEM AND METHOD FOR SELECTING SAME
Document Type and Number:
WIPO Patent Application WO/2014/061854
Kind Code:
A1
Abstract:
The present invention relates to a technique for estimating a precise angle-of-arrival (AOA) of a GPS, which removes inference from GPS reception signals influenced by intended or unintended interference, and estimates the precise angle-of-arrival of the GPS so as to efficiently receive data. A GPS angle-of-arrival selection system, according to the present invention, comprises: an AOA estimation unit which is connected with a reception antenna of a GPS receiver having at least one antenna array element and determines a first AOA of a received signal before despreading and a second AOA of a received signal after despreading; and an AOA selection unit for comparing the first AOA with the second AOA and selecting different peak values.
