Abstract

The invention discloses a method for estimating the angle of arrival in communication. The method includes: acquiring a wireless signal received by the array antenna in real time; inputting the wireless signal received by the array antenna in real time into an angle-of-arrival estimation model, and outputting a corresponding angle-of-arrival estimation result, wherein the angle-of-arrival estimation model uses training data The set is obtained through pre-training, and the training data set is used to characterize the mapping relationship between the wireless signal received by the array antenna and the angle of arrival in various communication scenarios. The invention can quickly and accurately estimate the angle of arrival of the communication process, and is especially suitable for rapidly changing communication scenarios.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically, to a method for estimating an angle of arrival in communication. Background technique [0002] In recent years, array signal processing technology has developed rapidly and has been widely used in communication, radar, astronomy and other fields. Angle of arrival estimation is one of the typical applications of array signal processing. [0003] For wireless communication systems, channel angle-of-arrival estimation plays an important role in many fields. For example, in smart antenna systems, angle-of-arrival estimation can reduce the complexity of beamforming designs. Especially for mmWave large-scale MIMO, if the angle of arrival information can be obtained, the beamforming through the control vector can obtain greater gain in the direction of signal arrival with lower complexity. Besides at the base station, angle of arrival estimation can also ...
