Abstract: How to extract the magnetocardiographic (MCG) signals from the noisy background is the key of MCG signal processing. In this paper, wavelet transformation is adopted to recover the MCG signals, acquired by using the high Tcc dc -SQUI D magnetometer developed at our institute. The results of this work show that t his method is much more effective than other methods used before and can be implemented in the MCG system for routing operation. This method can also be used in noise cancellation of other non-stationary signals.
