Abstract

The invention provides a signal separation method and device, electronic equipment and a medium. The method comprises the steps that a mixed signal is obtained, a source signal in the mixed signal has a sub-Gaussian attribute, hypothetical source signal kurtosis is obtained, and the absolute value of the hypothetical source signal kurtosis is larger than or equal to 0.5; assuming source signal kurtosis based on the mixed signal, and determining a separation matrix; increasing the absolute value of the assumed source signal kurtosis, re-determining the separation matrix based on the assumed source signal kurtosis after the absolute value is increased until the separation matrix corresponding to the assumed source signal kurtosis after the absolute value is increased is empty, and taking the previous separation matrix with the empty separation matrix as a signal separation matrix; and separating the mixed signal by using the signal separation matrix to obtain a source signal, so that the separation of the mixed signal can be realized.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a signal separation method, device, electronic equipment and medium. Background technique [0002] Due to the increasing popularity of informatization and intelligent construction in all walks of life today, the requirements for signal processing are also getting higher and higher. How to identify the required source signal from the collected mixed signal is an urgent problem to be solved. [0003] In the prior art, the source signal is usually identified by identifying the distinguishing features of the source signal, but when the distinguishing features of the source signal are unknown, the source signal cannot be identified. Contents of the invention [0004] The present application aims to provide a signal separation method, device, electronic equipment and medium, and proposes a method for separating source signals with unknown characteristics. [0005...
