Fast estimation of weak bio-signals using novel algorithms for generating multiple additional data frames

摘要

A method and apparatus for de-noising weak bio-signals that have a relatively low signal to noise ratio is disclosed. An iterative process of de-noising a data set comprised of a new set of frames is used. The method separately performs a non-linear de-noising operation on each of the component frames and combines the resultant de-noised frames to form a combined resultant de-noised input signal.
