Problems solved by technology
[0003] Due to the limited actual space, the volume of the antenna array cannot be very large
When the physical size of the antenna array is limited, the mutual coupling and interference between multiple antenna elements will inevitably lead to the degradation of antenna performance
At present, hardware decoupling methods are mostly used, such as setting defect decoupling around the antenna, setting up partitions, decoupling networks and other structures, but there are certain decoupling limits in the hardware decoupling scheme, and decoupling is generally performed in tight coupling situations. The efficiency is not high, and additional hardware needs to be set up, which increases the difficulty and pressure of antenna design

The embodiment of the invention discloses an antenna array decoupling method, device and system and a storage medium. The method comprises the steps of: receiving predetermined digital domain signals of a plurality of channels, each of the plurality of channels being a data channel corresponding to an array element in an antenna array; determining the decoupling coefficient of the channel participating in decoupling corresponding to each channel, wherein the decoupling coefficient is a coefficient obtained by solving in advance according to the measured in-array directional diagram information of each array element in the antenna array; and processing the predetermined digital domain signal of the channel participating in decoupling corresponding to each channel according to the decoupling coefficient to obtain the predetermined digital domain signal of each channel decoupling.
Description
Technical field [0001] Embodiments of the present invention relate to the field of communication technologies, in particular to an antenna array decoupling method, device, system, and storage medium. Background technique [0002] With the fifth-generation mobile communication system (The 5G) technology rapid maturation and application, it is necessary to make a faster data transfer rate, lower transmission delay, and higher reliability. In this context, 5G large-scale multi-input output technology (MIMO) can use multi-antennas to improve data throughput and stability of communication without increasing communication bandwidth. [0003] Due to the restricted actual space, the volume of the antenna array cannot be large. In the case of the physical dimension of the antenna array, the mutual coupling, interference between the plurality of antenna units will inevitably cause a decrease in antenna performance. Currently, a multi-hardware decoupling method is used, such as setting defe...
