Embodiment Construction

[0063] The inventors noticed in the process of the invention:

[0064] figure 1 Schematic diagram of multi-channel antenna test scheme, such as figure 1 As shown, in the multi-channel antenna test method, the input method of the control beam excipient weight is widely used is:

[0065] At the multi-channel antenna input with N input ports, a fixed beam excipient value of 1 point N is connected to a power divider, and the respective ports of the power separator are respectively input to the multi-channel antenna input to the multi-channel antenna. Value to achieve beam synthesis of multi-channel antennas, and test the synthetic beam pattern of multi-channel antennas.

[0066] However, since a power separator can only implement an input of a set of beam excipient weights, for multi-channel antennas, in order to complete the test of different synthetic beam directions, it is necessary to enter multi-group beam excipient values ​​in turn. Accordingly, there is a need for a plurality ...

Abstract

The invention discloses a multi-channel antenna test method, device and system and a medium. The method comprises the following steps: receiving a beam forming instruction and a radio frequency input signal sent by an external pattern test system; determining a beam forming weight used in the test according to the beam forming instruction; after the radio frequency input signals of all output ports of an output circuit are adjusted according to the beam forming weights, forming N paths of radio frequency output signals, wherein N is the number of channels of a multi-channel antenna; and sending the N paths of radio frequency output signals to the multi-channel antenna to be tested. According to the invention, the overall test efficiency can be greatly improved; connection errors caused by manual operation can be avoided, and the accuracy and objectivity of testing can be greatly improved; and the application range is wide and the test cost is reduced.

Description

Technical field [0001] The present invention relates to the field of wireless communication, and in particular, to a multi-channel antenna test method, apparatus, system, and medium. Background technique [0002] With the development of wireless communication technology, limited wireless frequency resources are facing continuously growing communication needs, more and more wireless communication systems introduce multi-channel antennas to enhance system capacity, coverage and system throughput. [0003] There are many technical indicators of multi-channel antennas, with an antenna direction map as an indicator of the radiant electromagnetic wave ability in space, which directly reflects the performance and working state of the multi-channel antenna. Therefore, in the entire network coverage project, testing for the antenna direction map is particularly important. [0004] The multi-channel antenna is in a variety of synthetic beams, such as a single-channel antenna, such as a sin...
