Abstract
A noise reduction method is disclosed that uses numerical logic to estimate the value of the noise in a receive system and remove the noise. A surrogate probe value is selected and subtracted from an input signal and an iterative process selects a noise probe value for each iteration and the respective noise probe values are summed resulting in a noise estimate that is combined with the input signal.
