Embodiment 1

[0045] figure 1 A flow of an antenna adjustment method for a MIMO microwave system provided by the first embodiment of the present invention is shown, and only parts related to the embodiment of the present invention are shown for convenience of description.

[0046] The antenna adjustment method of the MIMO microwave system provided by the implementation of the present invention is applied to the MIMO microwave system. The system includes four outdoor units, which are respectively the first unit to the fourth unit, and there is only one antenna of the outdoor unit. The antenna angles of the other three outdoor units are inconsistent, and the antenna adjustment method in this embodiment includes the following steps:

[0047] Step S101, configure the second outdoor unit to be in the transmitting state, configure the first outdoor unit and the third outdoor unit to be in the receiving state, and configure the other outdoor units to be in the non-transmitting state, wherein the a...

Abstract

The invention provides an antenna adjusting method and device for a multi-input and multi-output microwave system, which is suitable for the technical field of microwave antennas. The multi-input and multi-output microwave system comprises four outdoor units, wherein the antenna angle of only one outdoor unit is different from the antenna angles of the other outdoor units. The antenna adjusting method comprises the steps of configuring a second outdoor unit to be in a sending state, and configuring a first outdoor unit and a third outdoor unit to be in a receiving state; determining whether the difference value between the microwave signal power value received by the first outdoor unit and the microwave signal power value received by the third outdoor unit is larger than a certain threshold value; adjusting the antenna of a fourth outdoor unit if the difference value is smaller than the threshold value, so that the antenna angle of the fourth outdoor unit is the same as that of the other outdoor units. The invention is advantageous in that two outdoor units are combined, and the antenna angles can be determined to be consistent or not by determining the received side lobe signal, and thereby the antenna angles in the same site can be consistent.

Description

technical field [0001] The invention belongs to the technical field of microwave antennas, and in particular relates to an antenna adjustment method and device for a multi-input multi-output microwave system. Background technique [0002] Microwave technology is a wireless transmission method for transmitting data through space. It does not need to lay optical fibers or cables, etc. It has obvious engineering advantages in cities, remote areas or special areas (such as rivers, etc.); Flexible and short service provisioning time; with the development of microwave technology, the cost of microwave equipment is gradually reduced, so microwave technology is used more and more widely. [0003] Digital Microwave (Digital Microwave) is a system that transmits PDH (Pseudo-Synchronous Digital Hierarchy) and SDH (Synchronous Digital Hierarchy) signals wirelessly. A digital microwave system generally consists of two parts: an indoor unit (Indoor Unit, IDU) and an outdoor unit (Outdoor...
