Abstract

The invention relates to a gain control method and device for a digital repeater, the digital repeater and a storage medium. The method comprises the steps of obtaining an expected attenuation value of a user; Determining a first attenuation value and a second attenuation value according to the expected attenuation value and a preset first mapping relation, Wherein the first mapping relationship comprises a corresponding relationship between a plurality of nominal attenuation values and actual attenuation values, the first attenuation value is an actual configuration attenuation value of a first attenuator in an analog domain of the digital repeater, and the second attenuation value is an actual configuration attenuation value of a second attenuator in a digital domain of the digital repeater; And performing gain control on the digital repeater in the analog domain and the digital domain according to the first attenuation value and the second attenuation value. According to the method,the gain control precision of the digital repeater can be improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a digital repeater gain control method, device, digital repeater and storage medium. Background technique [0002] A repeater is a wireless signal relay product that expands the distance of network transmission by resending or forwarding data signals. With the continuous development of communication technology, the accuracy of the coverage of the repeater is required to be more and more precise. Therefore, the accuracy of the gain control of the repeater is increasingly required. [0003] In the traditional technology, the control of the gain of the repeater is generally realized in the analog domain of the repeater. The specific control method is: by setting the attenuator in the repeater, and setting the user's expected attenuation value to the analog domain The attenuator reduces the gain multiple of the repeater through the attenuator, so as to realize the gain control...
