A multi-channel noise analysis system and its analysis method

Abstract

The invention discloses a multi-channel noise analysis system and its analysis method, comprising a sending end, a receiving end, a noise monitoring end and a remote data processing terminal, the sending end and the receiving end are electrically connected through a channel, and the noise The input terminal of the monitoring terminal is electrically connected to the channel through a detection line, and the noise monitoring terminal is composed of N monitoring sub-terminals, and the N monitoring sub-terminals are connected through wireless signals. The present invention relates to the technical field of channel noise analysis. The multi-channel noise analysis system and its analysis method, by setting the noise monitoring terminal to detect the stability of signal transmission in the channel, can identify and calculate the strength and type of channel noise and other information, and bind and code the transmission signal, through the noise Comparing the encoded data fed back by the monitoring end with the source data sent by the sending end can determine whether the noise interferes with the signal transmission. The two aspects of detection can more comprehensively analyze the impact of channel noise on signal transmission.

Description

technical field [0001] The invention relates to the technical field of channel noise analysis, in particular to a multi-channel noise analysis system and an analysis method thereof. Background technique [0002] Channel refers to the signal channel based on the transmission medium. According to the definition of the channel, if the channel only refers to the transmission medium of the signal, this channel is called a narrow channel; if the channel is not only the transmission medium, but also includes some conversion devices in the communication system , such a channel is called a generalized channel. The channel is an essential part of the communication system, and any communication system can be regarded as composed of three parts: the sending device, the channel and the receiving device. The channel usually refers to the signal channel based on the transmission medium, and it is unavoidable for the signal to encounter noise in the channel transmission, that is, the chann...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a multi-channel noise analysis system and its analysis method, which solves the problem that the existing channel noise detection system generally only detects the influence of channel noise on the signal at the channel receiving end, and cannot judge The area where the noise is generated is not convenient for better protection, and generally cannot detect multi-channel data stably at the same time. At the same time, the existing detection system only detects the intensity of channel noise and cannot comprehensively analyze the impact of noise on data transmission. The question of the impact
