Experiments with extrapolation of band-limited signal
M. Tsai, D. O'Connor · 2005
The ill-conditioned nature of the band-limited signal reconstruction problem is illustrated and analyzed. The singular value decomposition (SVD) truncation method is proposed for obtaining approximate solutions. The proper selection of the SVD terms is a balance between truncation error and the error produced by the measurement noise. Selection rules based on certain apriori information are outlined and demonstrated.
