Low-voltage power line carrier channel noise classification modeling method and device and storage medium

The invention discloses a low-voltage power line carrier channel noise classification modeling method and device and a storage medium, and the method comprises the steps: separating noise components contained in externally input channel noise, and obtaining the noise components; and determining parameters of a noise model corresponding to the noise component based on the probability density distribution function to obtain the noise model corresponding to the noise component. According to the method, noise in the channel is stripped and modeled in sequence through extraction, separation and classification modeling of the noise, so that modeling of common noise such as impulse noise, power frequency synchronous noise, power frequency asynchronous noise, narrow-band noise and colored background noise in the power line channel is realized; according to the method, information such as noise types and features in actual channels can be accurately described, the model complexity is low, the fitting degree with actua
