Document Type and Number:
WIPO Patent Application WO/2019/127491
Kind Code:
A1
Abstract:
The present invention relates to the technical field of communications. Provided are a device and method for correcting a deviation between multiple arrays of transmission channels capable of realizing online correction for multiple arrays of transmission channels. The multiple arrays include a first array, a second array and a third array which are cascaded. The multiple arrays comprise two cascades of transmission channels which respectively connected to a first end point and a second end point of a correction coupling channel. The device comprises: a vector measurement unit used to measure a signal vector according to feedback signals from the two cascades of transmission channels upon feeding of a first signal at the first end point, and to measure a signal vector according to feedback signals from the two cascades of transmission channels upon feeding of a second signal at the second end point; a processing unit used to determine, according to the measured signal vectors, a deviation correction value for the two cascades of transmission channels; and a correction unit used to set the deviation correction value in the first array to correct a deviation between the two cascades of transmission channels.
