Sampling With Finite Rate of Innovation: Channel and Timing Estimation for UWB and GPS

Abstract—In this work, we consider the problem of channel estimation by using the recently developed theory for sampling of signals with a finite rate of innovation [1]. We show a framework which allows for lower than Nyquist rate sampling applicable ...

Quantitative Fourier Analysis of Approximation Techniques: Part II—Wavelets

Michaël Unser, Thierry Blu

In a previous paper, we proposed a general Fourier method which provides an accurate prediction of the approximation error, irrespective of the scaling properties of the approximating functions. Here, we apply our results when these functions satisfy the u ...

The commutativity of up- and down-sampling in two dimensions

Martin Vetterli

The authors state and prove a theorem solving the problem of commutativity in two dimensions. It is shown under which conditions upsampling and downsampling can be interchanged in two dimensions. This is the generalization to arbitrary two-dimensional latt ...

Theory of two-dimensional multirate filter banks

Martin Vetterli

Results are presented on 2-D FIR (two-dimensional finite-impulse-response) filter banks for multirate applications. The theory is valid for all sampling lattices; conditions for alias-free and perfect signal reconstruction are derived. Synthesis structures ...
