Abstract

The disclosure relates to an impulse noise estimation method, device, storage medium and electronic equipment, which solves the technical problem in the related art that the power line communication system is limited in the data transmission process due to the inability to accurately estimate the impulse noise. The method includes: receiving a data packet, obtaining an initial time-domain signal of the data packet; performing Fourier transform on the initial time-domain signal to obtain an initial frequency-domain signal; performing zero-setting processing on the initial frequency-domain signal, and performing an inverse Fourier transform to obtain a first time-domain signal; performing channel equalization processing on the initial frequency-domain signal to obtain a second frequency-domain signal; obtaining the pulse information of the data packet according to the first time-domain signal, according to Performing norm calculation on the pulse information and the second frequency domain signal to obtain a plurality of norm values; determining the minimum norm value from the plurality of norm values, and obtaining according to the amplitude of the impulse noise corresponding to the minimum norm value An estimate of the impulse noise of the packet.

Description

technical field [0001] The present disclosure relates to the technical field of power line communication, and in particular, to an impulse noise estimation method, device, storage medium and electronic equipment. Background technique [0002] In the power line communication system, there is high-power burst noise, which will cause transmission errors to the transmitted data packets during data transmission. [0003] In related technologies, the signal polluted by impulse noise is mainly identified through the amplitude information in the time domain, and its amplitude is limited to a fixed value or set to zero, that is, the method of limiting and zeroing to reduce the impulse noise, but regardless of the limit Both the amplitude and the zero setting need to accurately estimate a threshold, through which the prepayment and zero setting can be performed, and the pulse noise cannot be accurately estimated, which leads to the limitation of the power line communication system in ...
