Problems solved by technology

However, signals of different standards have different signal characteristics such as data rate and data bit width. Therefore, the implementation methods of DAGC for signals of different standards are also quite different.
[0004] To sum up, the existing technology designs DAGC separately for signals of different standards, and each standard corresponds to a set of logic resources, resulting in waste of resources, cumbersome parameter configuration, inconsistent processing delay, complex timing, and design and development work. large amount

Abstract

The invention discloses a method and a device for multinuclear automatic gain control, belonging to the field of gain control. The method comprises the following steps of: converting parallel data into serial data, wherein the parallel data comprise different-standard type data carried by all channels; configuring all the passages in a polling list; and carrying out gain control on the serial data according to the polling list. The device comprises a parallel and serial converting module, a configuring module and a gain control module. The invention realizes that various standard types multiplex a set of logical resource by using the method, greatly saves the logic resource, and simplifies configuring work, and the converted serial data of all the channels can use one timing signal; and the processing time delays of different channels are consistent, which is convenient for management and maintenance.

Description

technical field [0001] The invention relates to the field of gain control, in particular to a method and device for multi-core automatic gain control. Background technique [0002] A modern digital-analog hybrid receiver usually includes three parts: RF (Radio Frequency, analog radio frequency), IF (Intermediate Frequency, digital intermediate frequency), and BB (Base Band, digital baseband). In order to reduce the calculation amount of the baseband demodulation and the data bit width of the intermediate frequency output, there is a DAGC (Digital Auto Gain Control, digital domain automatic gain control) module before the baseband demodulation, the DAGC module performs automatic gain adjustment on the input signal, and the output Adjust the power to near the target power. [0003] A common DAGC implementation solution is to use a logic module for signals of different formats. However, signals of different standards have different signal characteristics such as data rates an...
