#### Cost-efficient approximation of linear systems with repeated and multi-channel filtering configurations

(IEEE, 1998-05)

It is possible to obtain either exact realizations or useful approximations of linear systems or matrix-vector products arising in many different applications, by synthesizing them in the form of repeated or multi-channel ...

#### Assessment of information redundancy in ECG signals

(IEEE, 1997-09)

In this paper, the morphological information redundancy in standard 12 lead ECG channels is studied. Study is based on decomposing the ECG channels into orthogonal channels by an SVD based algorithm and then reconstructing ...

#### Applications of the fractional Fourier transform in optics and signal processing-a review

(SPIE, 1996)

The fractional Fourier transform The fractional Fourier transform is a generalization of the common Fourier transform with an order parameter a. Mathematically, the ath order fractional Fourier transform is the ath power ...

#### A reduction in the number of active components used in transconductance grounded capacitor filters

(IEEE, 1990)

The number of active components in transconductance grounded capacitor filters is reduced. This reduction is possible in the case where capacitor loops and/or inductor cutsets exist in LC-ladder prototype. A more significant ...

#### Markov modulated periodic arrival process offered to an ATM multiplexer

(IEEE, 1993-11-12)

When a superposition of on/off sources is offered to a deterministic server, a particular queueing system arises whose analysis has a significant role in ATM based networks. Periodic cell generation during active times is ...

#### Adaptive filtering approaches for non-Gaussian stable processes

(IEEE, 1995-05)

A large class of physical phenomenon observed in practice exhibit non-Gaussian behavior. In this paper, α-stable distributions, which have heavier tails than Gaussian distribution, are considered to model non-Gaussian ...

#### Linear/nonlinear adaptive polyphase subband decomposition structures for image compression

(IEEE, 1998-05)

Subband decomposition techniques have been extensively used for data coding and analysis. In most filter banks, the goal is to obtain subsampled signals corresponding to different spectral bands of the original data. ...

#### The discrete fractional Fourier transformation

(IEEE, 1996)

Based on the fractional Fourier transformation of sampled periodic functions, the discrete form of the fractional Fourier transformation is obtained. It is found that only for a certain dense set of fractional orders such ...

#### Wide-band maximum likelihood direction finding by using tree-structured EM algorithm

(IEEE, 1996)

A tree structured Expectation Maximization (EM) algorithm is proposed and applied to the wide-band angle of arrival estimation. It may be seen as a generalization on EM using the ideas of Cascade EM algorithm and Space ...

#### A wavelet based recursive reconstruction algorithm for linear measurements

(IEEE, 1996)

A recursive algorithm is proposed to obtain an efficient regularized least squares solution to large linear system of equations which arises in many physical measurement models. The algorithm recursively updates the solution ...
