Method and system for reconstructing random pulse disturbance signal

Abstract

The invention provides a method and a system for reconstructing a random pulse disturbance signal, belongs to the technical field of rail transit pulse signal acquisition, and is used for representing random pulse characteristics of a random pulse interference effect: link error rates of different modulation wireless links under pulse interference are represented by using amplitude probability distribution of pulse disturbance; representing block error rates of different coding wireless links under pulse interference by using pulse duration distribution; based on the random pulse characteristic and the time-frequency characteristic of the pulse interference effect, deep characteristic extraction is carried out, a neural network model is constructed, and a random pulse conversion circuit is constructed; according to random pulse characteristics, on the basis of a standard square wave, random discharge pulse disturbance is constructed based on a random pulse conversion circuit, and reconstruction of a random pulse disturbance signal in a complex electromagnetic environment is realized. According to the method, the pulse signal with specific envelope, spectrum width and statistical characteristics is obtained, so that the accuracy of a simulation result is ensured; and reliable simulation of random discharge pulse disturbance in different situations is realized.
