Discrete- and continuous-time local cosine bases with multiple overlapping

Cosine-modulated filter banks (CMFB’s) are filter banks whose impulse responses are obtained by modulating a window with cosines. Among their applications are video and audio compression and multitone modulation. Their continuous- time counterpart is known ...

Acoustico-articulatory inversion of unequal-length tube models through lattice inverse filtering

Sacha Krstulovic

Constraints related to the Distinctive Regions and Modes (DRM) speech production model are incorporated in the framework of speech analysis by inverse filtering. It is shown that the analogy between Auto-Regressive modeling and acoustic models based on aco ...

Discrete-Time Wavelet Extrema Representation - Design and Consistent Reconstruction

Martin Vetterli

The paper studies wavelet transform extrema and zero-crossings representations within the framework of convex representations in L(Z). Wavelet zero-crossings representation of two-dimensional signals is introduced as a convex multiscale edge representation ...

Deterministic analysis of oversampled A/D conversion and decoding improvement based on consistent estimates

Martin Vetterli

is paper deals with the deterministic analysis of oversampled A/D conversion (ADC), the properties derivable from such an analysis, and the consequences on reconstruc- tion using nonlinear decoding. Given a bandlimited input X producing a quantized version ...

Interferences in adiabatic transition probabilities mediated by Stockes lines

Charles Pfister

We consider the transition probability for two-level quantum-mechanical systems in the adiabatic limit when the Hamiltonian is analytic. We give a general formula for the leading term of the transition probability when it is governed by N complex eigenvalu ...
