Simple Carrier Frequency Offset Estimators in Frequency Flat-Fading Channels
— In this paper, the Nonlinear Least-Squares (NLS) estimator for frequency offset in flat-fading channels is systematically derived. A simple interpolation technique is introduc...

Randomized motion estimation
Motion estimation is known to be a non-convex optimization problem. This non-convexity comes from several ambiguities in motion estimation such as the aperture problem, or fast mo...

A spectral approach to recursive end-to-end distortion estimation for sub-pixel motion-compensated video coding
Error resilient video coding critically relies on the accuracy of endto-end distortion estimation. An established solution, the recursive optimal per-pixel estimate (ROPE), is bas...
