Embodiment Construction

[0026] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] The following description is made by applying the multi-beam antenna device with multiple beams according to the present invention to the UTStarcom company base station which has been widely used at present. However, as mentioned above, this does not constitute a limitation of the present invention.

[0028] image 3 The system structure of an embodiment of the multi-beam antenna system of the present invention is shown, which is fully compatible with the existing base station structure. like image 3 As shown, the multi-beam antenna implemented by the beamforming module 1 receives wireless signals from different directions and different polarization modes, and sends them to the beam switching processing module 3; Corresponding processing is performed, and these processing results finally guide the beam switching module 3 to perfo...

Abstract

The apparatus is composed of the narrow beam antenna of different direction and predetermined number, between the narrow beam antenna of same direction, the polarization diversity is achieved to supply the antenna system of multiple beam. In addition, the signal processing method is supplied to execute the balanced receiving on up-run multi-beam signal. The invention enlarges the coverage area, improves the system capacity and the efficiency of utilization.

Description

technical field [0001] The present invention generally relates to the field of wireless communication, and more specifically relates to the use of multi-beam antennas in smart antennas instead of antennas in the original system in wireless communication systems to improve spectrum utilization efficiency, increase system capacity, and reduce Interference method and device. The invention also relates to a signal processing method and device for automatically optimizing transmission and reception patterns in a wireless communication system. Background technique [0002] The smart antenna uses digital signal processing technology to generate spatially directional beams, so that the main beam of the antenna is aligned with the arrival direction of user signals, and the side lobes or nulls are aligned with the arrival direction of interference signals, so as to fully and efficiently utilize mobile user signals and delete or suppress interference signals. Purpose. Compared with o...
