Abstract
An improved and computationally efficient signal processing is provided to estimate and reduce noise in a sampled signal. Hence, a first filter recursive filters a vector in the signal in one direction along the vector, a second filter recursive filters the vector in the opposite direction to the first filter along the vector, and a combining section combines the results of the first and second filters. Coefficients of the first and second filters are dependent on a position in the vector.
