Application of the matching pursuit method in a fetal phonocardiographic telemedicine system.
A novel compact method for fetal home monitoring optimized for long data acquisition time has already been presented. The method involves preprocessing a disturbed acoustic signal received on the maternal abdomen. The present work summarizes phenomena encountered during analysis of the incoming PCG signal, and describes further improvements made to the analysis system already in use including the application of the MP method to determining heartbeat lengths and identifying murmurs between heart sounds.
