A method and apparatus for de-noising weak bio-signals having a relatively low signal to noise ratio utilizes an iterative process of wavelet de-noising a data set comprised of a new set of frames of wavelet coefficients partially generated through a cyclic shift algorithm. The method preferably operates...http://www.google.com.au/patents/US7054454?utm_source=gb-gplus-sharePatent US7054454 - Fast wavelet estimation of weak bio-signals using novel algorithms for generating multiple additional data frames
