Methods, systems and computer program products for extracting paroxysmal events from signal data using multitaper blind signal source separation analysis

摘要

Methods, systems and computer program products for extracting paroxysmal events from signal data using multitaper blind signal source separation analysis are disclosed. According to one method, a signal data set including signal data from a plurality of channels is received. Blind signal source separation analysis is repeatedly performed on different time limited segments across the signal data in a multitaper method to extract a plurality of components indicative of paroxysmal events from the signal data. The components indicative of paroxysmal events are presented to a user.
