Abstract

The invention provides a digital-analog hybrid beamforming multichannel correction method and device. The method comprises the following steps: when multiple channels are in an offline state, executing the following correction method: testing amplitude-phase parameters of m * n arrays in a sub-array corresponding to each channel; selecting one array element from the oscillators of the tested sub-array as a reference array element; determining phase and amplitude differences between the reference array element and other array elements, and compensating based on the phase and amplitude differences, wherein m and n are positive integers; under the condition that multiple channels are in an online state, the following correction method is executed: the amplitude-phase value of each channel andthe amplitude-phase value of the respective correction channel are obtained, and the amplitude-phase difference between the amplitude-phase value of each channel and the amplitude-phase value of thecorresponding correction channel is determined, and adjusting the phase weight of each channel based on the amplitude difference so as to enable the phase and amplitude of each channel to be consistent. Through the method and the device, the problem that a scheme for effectively correcting the beamforming channel does not exist in related technologies is solved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a digital-analog hybrid beamforming multi-channel correction device method and device. Background technique [0002] 5G is the fifth generation mobile communication network, and its core technologies include high frequency band, large bandwidth, multiple antennas and beamforming. Beamforming is a key technology that determines the 5G system architecture and is the most difficult to implement. [0003] Beamforming is based on the signal preprocessing technology of the antenna array. By adjusting the phase weight of each element in the antenna array to generate a directional beam, it can obtain obvious array gain and realize functions such as beam scanning and beam tracking. Therefore, the beamforming technology has great advantages in expanding the coverage area, improving the edge throughput, and suppressing interference, etc., but there is no solution for effectively correcti...
