We present a method to remove the effects of sensor-specific noise in multiple-channel recordings such as magnetoencephalography (MEG) or electroencephalography (EEG). The method assumes that every source of interest is picked up by more than one sensor, as is the case with systems with spatially dense sensors. To reduce noise, each sensor signal is projected on the subspace spanned by its neig...
Suppression of noise and artifacts is a necessary step in biomedical data processing. Adaptive filtering is known as useful method to overcome this problem. Among various contaminants, there are some situations such as electrical activities of muscles contribute to impulsive noise. This paper deals with modeling real-life muscle noise with α-stable probability distribution and adaptive filterin...
Handset-free mobile speech communication in a noisy environment requires robust noise suppression with minimal speech degradation. Two solutions for the noise suppression problem are available: either the noise suppression module precedes the speech coder or noise suppression is integrated into the speech coder. Both solutions have been tested with signals picked up in a car under the same cond...
