Abstract

Blind Source separation has been applied to a whole range of different problem using an antenna array. Many biomedical designs for hearbeat separation already have been proposed [1], where the operational setup consists of disposing several patches on the pregnant woman in order to monitor remotely the heartbeat of the fetus. Alternatively, a Doppler radar can monitor heart beat in applications as post-disaster emergency rescue situations, counter-terrorism measures, and hospital medical monitoring. One problem is to isolate and separate heart beat from several subjects. In this paper we present our algorithm based on ACMA [2] and evaluate it though simulations.
