Solution Overview
Problem
Existing amplitude-phase tracking technologies in wireless communication systems face limitations in supporting both single-channel broadband and narrow-band amplitude-phase tracking, and have poor universality and expandability, making them difficult to adapt to varying demands.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If dedicated digital circuit solutions are used for single-channel broadband or narrow-band amplitude-phase tracking, then implementation simplicity is improved, but universality and expandability deteriorate
Solution Approach 1:
The calibration system is divided into multiple independent basic units, each capable of processing one signal channel. These basic units can be selectively activated and configured based on whether single-channel broadband or multi-channel narrow-band tracking is needed, allowing the system to adapt to different application scenarios without requiring complete redesign.
Solution Approach 2:
The patent designs a universal calibration apparatus that can perform both single-channel broadband amplitude-phase tracking and multi-channel narrow-band amplitude-phase tracking. By configuring multiple basic units with selectable connections, the same hardware platform serves multiple functions, eliminating the need for separate dedicated circuits for different applications.
2Device complexity
If the system is configured for fixed demands, then implementation complexity is reduced, but expandability deteriorates
Solution Approach 1:
The system employs dynamic configuration capabilities where basic units can be selectively activated or deactivated based on demand. The connection relationships between basic units and signal channels are not fixed but can be reconfigured through control logic, allowing the system to expand from single-channel to multi-channel operations and adapt between broadband and narrow-band modes without hardware changes.

AI summary
Embodiments of the present disclosure provide an amplitude and phase calibration method and device, a storage medium, and an electronic device. The method includes: receiving a plurality of signals to be calibrated, with the plurality of signals to be calibrated being signals of one or more digital channels; routing the plurality of signals to be calibrated to a plurality of basic units, with each of the basic units configured to process one of the signals to be calibrated; and performing amplitude and phase calibration on the plurality of signals to be calibrated by the plurality of basic units. The present disclosure can solve the problems in the related technology that related solutions merely support single-channel broadband amplitude-phase tracking or merely support narrow-band amplitude-phase tracking, are difficult to expand once demands are fixed, and have relatively poor universality, flexibly select data input into a basic computing unit, realize flexible configuration according to different demands, and improve universality and expandability of system.
