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 ...

Optimal Smoothing for Guaranteed Service

Jean-Yves Le Boudec, Olivier Verscheure

We consider a scenario where multimedia data is sent over a network offering a guaranteed service such as ATM VBR or the guaranteed service of the IETF. A smoothing device writes the stream into a networking device for transmission, possibly with some pre- ...

Oversampled Filter Banks

Martin Vetterli

Perfect reconstruction oversampled filter banks are equivalent to a particular class of frames in t(2)(Z), These frames are the subject of this paper. First, necessary and sufficient conditions on a filter bank for implementing a frame or a tight frame exp ...

Investigation of a possible process identity between DRM and Linear Filtering

Sacha Krstulovic

The classical analogy between linear filtering and acoustical filtering by tubes is applied in the non-classical case where the tubes are made of unequal-length sections (such as the DRM case). It is shown that the filtering process identity is substantial ...

Recursive Algorithms for Identification in Closed Loop - A Unified Approach and Evaluation

Alireza Karimi

A unified presentation of recursive algorithms for plant model identification in closed loop is given. From the basic formulation of the problem of finding the plant model that gives the best predictor for the closed-loop system, two families of algorithms ...

Hoo optimality of the LMS algorithm

Ali H. Sayed

We show that the celebrated least-mean squares (LMS) adaptive algorithm is H/sup /spl infin// optimal. The LMS algorithm has been long regarded as an approximate solution to either a stochastic or a deterministic least-squares problem, and it essentially a ...

Modified FxLMS algorithms with improved convergence performance

Ali H. Sayed

This paper proposes two modifications of the FxLMS algorithm with improved convergence behaviour albeit at the same computational cost of 2M operations per time step as the original FxLMS update. The paper further introduces a generalized FxLMS recursion a ...

Two-stage Wiener filter based cancellation receivers for DS-CDMA

Michael Christoph Gastpar

The authors present the two-stage Wiener filter based cancellation receiver for DS-CDMA, i.e. a receiver using Wiener filters to regenerate the interferers and to make the final despreading. Theoretical calculation as well as simulation results will show t ...

A robustness analysis of Gauss-Newton recursive methods

Ali H. Sayed

We provide a time-domain robustness analysis of Gauss-Newton recursive methods that are often employed in identification and control. Several free parameters are included in the filter description while combining the covariance update and the weight-vector ...

Local and global passivity relations for Gauss-Newton methods in adaptive filtering

Ali H. Sayed

We provide a time-domain analysis of the robustness and stability performance of Gauss- Newton recursive methods that are often used in identification and control. Several free parameters are included in the filter description while combining the covarianc ...
