Embodiment Construction

[0043] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0044] The invention provides a method for intelligently estimating the angle of arrival of a separate digital-analog hybrid antenna system. The problem of phase ambiguity.

[0045] The embodiment of the present invention discloses a method for intelligently estimating the angle of arrival of a separate digital-analog hybrid antenna system. This method is divided into two processes: the offline training process of the model and the angle prediction process, such as figure 1 shown. The offline training process of the model is as follows: firstly, the whole space is divided into multiple sub-regions according to the codebook set; then, a training sample set is constructed for each spatial sub-region; Regional angle of arrival prediction model. The angle prediction process is as follows: First, each subarray at the receiving end selects differen...

Abstract

The invention discloses a method for intelligently estimating the angle of arrival of a separated digital-analog hybrid antenna system. In the method, the signal source transmits a signal, and the receiving end adopts a separated digital-analog hybrid antenna structure. At the same time, the whole technical solution is divided into two processes: The offline training process of the model and the angle prediction process. Compared with the existing technology, the solution provided by the present invention makes full use of the space and time resources of the system, and can achieve accurate angle of arrival in a low-complexity wide-area range without any prior information of the incoming wave At the same time, it effectively solves the problem of phase ambiguity in traditional algorithms.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for intelligently estimating the angle of arrival of a separated digital-analog hybrid antenna system. Background technique [0002] The rapid development of wireless communication technology has profoundly changed people's production and lifestyle, greatly promoted social change and innovation, and has become an indispensable part of today's world. Multiple Input and Multiple Output (MIMO) technology is a major breakthrough in the field of wireless communication smart antennas, which can double the capacity of communication systems without increasing bandwidth. With the vigorous development of the mobile Internet and the sharp increase in the amount of mobile data and the number of access devices, how to further meet the continuously increasing rate requirements of wireless communication has become a key issue for future mobile communication technologies....
