Abstract
An analysis is presented of the degradation introduced by using an interpolated FIR filter in the Wiener filtering structure. Applications such as channel equalization and echo cancellation are considered. The proposed degradation measure is a function of the input signal correlation, of the sparseness degree, and of the interpolator. It results from a joint approach combining interpolated transversal filtering and linearly-constrained optimization.
