DIGITAL-ANALOG HYBRID BEAMFORMING MULTI-CHANNEL CORRECTION METHOD AND DEVICE

摘要

The present application provides a digital-analog hybrid beamforming multi-channel correction method and device. The method comprises: when multiple channels are offline, executing the following correction method: testing amplitude and phase parameters of m*n elements in a subarray corresponding to each channel, selecting an element from the elements in the tested subarray as a reference element, determining phase and amplitude differences between the reference element and other elements, and performing compensation on the basis of the phase and amplitude differences, m and n being positive integers; and when multiple channels are online, executing the following correction method: obtaining an amplitude and phase value of each channel and an amplitude and phase value of a respective correction channel, determining an amplitude and phase difference between the amplitude and phase value of each channel and the amplitude and phase value of the respective correction channel, and adjusting a phase weight of each channel on the basis of the amplitude and phase difference to make the phase and amplitude of each channel consistent. By means of the present application, the problem in the related art that there is still no effective beamforming channel correction solution is solved.
