A method based on wavelet transform to reduce 1/f noise.
In this paper a method for reducing white noise and 1/f noise is investigated. Instead of modifying the hardware design of SQUID detector, we seek to reduce 1/f noise by the wavelet transform approach, which statistical characteristics in the wavelet domain are used. By applying this method to the simulated noise MCG-signal, we demonstrate that both the white noise and the 1/f noise can be significantly reduced.
