Title:
METHOD AND DEVICE FOR EXTRACTING BROADBAND ERROR CALIBRATION PARAMETERS AND COMPUTER-READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/098524
Kind Code:
A1
Abstract:
Disclosed in the present document are a method and device for extracting broadband error calibration parameters and a computer-readable storage medium, the method comprising: carrying out frequency band cutting for link broadband signals of an ultra-broadband system according to a received frequency band index table so as to generate sub-frequency bands; extracting the amplitude error and phase error of each sub-frequency band; according to the frequency band index table and a preset broadband weighting table, iteratively weighting the amplitude error and phase error of each sub-frequency band one by one respectively and accumulating same into initial amplitude error compensation parameters and initial phase error compensation parameters, and then combining said parameters and extracting broadband error calibration parameters.
