A Technique for Foreground Subtraction in Redshifted 21 cm Observations
, 2012 One of the main challenges for future 21 cm observations is to remove foregrounds which are several orders of magnitude more intense than the HI signal. We propose a new technique for removing foregrounds of the redshifted 21 cm observations. We consider
