Abstract

The embodiment of the invention discloses a method and a device for generating broadcast beam weight of an intelligent antenna array. The method mainly comprises the following steps of: determining a calculation formula of an array response vector of the intelligent antenna array according to the form of the intelligent antenna array; determining the array response vector of each angle in the preset angle sequence through the calculation formula of the array response vector; and generating the broadcast beam weight of the intelligent antenna array through the array response vector of each angle in the angle sequence. Due to the application of the technical scheme, the method and the device have the advantages of simplifying and unifying the generating process of the broadcast beam weight of the intelligent antenna array, not needing storing the weight data of a plurality of manufacturers largely in the manufacturing and configuring processes of the intelligent antenna, reducing occupied data storage space, reducing the complexity of data design and calculation in the realizing process of the system and improving the efficiency of generating the broadcast beam weight by the system.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for generating a smart antenna array broadcast beam weight. Background technique [0002] With the continuous development of wireless communication technology, limited wireless frequency resources are facing ever-increasing communication demands. Smart Antennas can alleviate this contradiction to a certain extent. The smart antenna system can use the combination of multiple antenna elements for signal processing, and automatically adjust the transmission or reception pattern to achieve the best performance for different signal environments. The resulting smart antenna array is the key technology in the TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) system. [0003] A smart antenna is a two-way antenna installed on the site of a base station. It obtains directivity through a set of fixed antenna units with programmable electronic ph...
