Abstract

The embodiment of the invention provides a communication assembly and a signal calibration system and method. The communication assembly comprises an antenna group, a line selector and a signal processor; the line selector is in communication connection with the antenna group and the signal processor; in a working state, the plurality of antennas in the antenna group are in one-to-one correspondence signal communication with the plurality of channels of the signal processor through the line selector; in a signal calibration state, the line selector is in signal communication with one antenna in the antenna group and each channel of the signal processor one by one, and is used for cooperating with the detector to realize signal measurement of each channel of the signal processor through communication connection with one antenna in the antenna group; the signal processor is provided with a first interface, and the first interface is used for being in communication connection with an upper computer, so that signal calibration of a corresponding channel of the signal processor is realized according to a signal value measured by the detector. According to the embodiment of the invention, deviation compensation can be carried out aiming at the difference of all channels, the compensation precision is improved, and the detection operation is simplified.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular, the present application relates to a communication component, a signal calibration system and a method thereof. Background technique [0002] In order to improve signal reception sensitivity or information throughput rate, existing communication terminals often adopt MIMO (multiple input multiple output) technology, that is, an antenna system that forms multiple channels between transceivers. [0003] Due to hardware differences in the production of communication terminals, it is inevitable that there will be deviations in the sending and receiving parameters of each channel. In order to ensure that the performance of each channel of the communication terminal remains consistent at the factory, calibration is usually required to compensate. However, the existing MIMO calibration scheme is restricted by the detection space and detection cost, and it is difficult ...
