Abstract

The invention provides a noise reduction method and a system based on the analysis of a channel signal-to-noise ratio. The method comprises the following steps: S1, SNR simulation is carried out to separate the contribution amount of crosstalk components contained in the noise; S2, the crosstalk is defined and the signal-to-noise ratio is calculated; 3, set parameters of Tx and Rx, and obtain waveforms of NEXT and FEXT by signal simulation; S4, according to the waveform signal value, the signal line which does not satisfy the signal-to-noise ratio condition is modified again. The embodiment ofthe invention redefines the SNR simulation principle, and includes the situations to be considered in the signal simulation process through two signal simulations, and the signal spectrum and the crosstalk spectrum are expressed in the form of integration, and the signal spectrum and the crosstalk spectrum are extended by half a byte forward and backward with the peak value as the center. Throughthe signal simulation results, the NEXT, FEXT waveform values are expressed concretely, and the signal lines that do not meet the signal-to-noise ratio are modified, so as to reduce the signal noise,and focus on the signal that does not meet the requirements of the management and control.

Description

technical field [0001] The invention relates to the technical field of server signals, in particular to a noise reduction method and system based on analyzing channel signal-to-noise ratio. Background technique [0002] Signal-to-noise ratio, the English name is called SNR or S / N (SIGNAL-NOISERATIO), also known as signal-to-noise ratio. Refers to the ratio of signal to noise in an electronic device or electronic system. [0003] The signal here refers to the electronic signal from the outside of the device that needs to be processed by this device, and the noise refers to the irregular extra signal (or information) that does not exist in the original signal generated after passing through the device, and this kind The signal does not change with the original signal. [0004] The goal of high-speed channel design is to reduce the loss and distortion of the signal during transmission, that is, to ensure that the effective components of the signal are as much as possible and ...
