Patent ID: 11700034

Abstract:
The present disclosure discloses a method and a device for extracting broadband error calibration parameters, and a computer-readable storage medium. The method includes: performing frequency band splitting on link broadband signals of an ultra-wide band system according to a received frequency band index table to generate sub-bands; extracting an amplitude error and a phase error of each sub-band; and iteratively weighting and accumulating, according to the frequency band index table and a preset broadband weight table, the amplitude error and the phase error of each sub-band one by one to an initial amplitude error compensation parameter and an initial phase error compensation parameter respectively, to synthesize and extract broadband error calibration parameters. The present disclosure can adaptively match a working bandwidth of the current ultra-wide band system, and perform iterative solution on error parameters of a working area in real time, thereby having the advantages of ultra-wide band, high performance, low power consumption and high flexibility.
