Title:
METHOD AND APPARATUS FOR ESTIMATING ANGLE OF ARRIVAL, AND TERMINAL, BASE STATION AND COMPUTER STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2018/028398
Kind Code:
A1
Abstract:
The present disclosure relates to a method and apparatus for estimating an angle of arrival, and a terminal, a base station and a computer storage medium. The method comprises: acquiring a time domain channel response of a communication channel; according to the time domain channel response, calculating an autocorrelation function of a channel response; and according to the autocorrelation function, constructing a cost function using an angle as an input parameter, and selecting an angle parameter value corresponding to the maximum value of the cost function as an angle-of-arrival estimation result. The method for estimating an angle of arrival in the present invention can accurately estimate an angle of arrival in the situation of a multi-path, reduces the estimation error of the angle of arrival, and improves the communication system transmission performance.
