#### A Class of Square Root and Division Free Algorithms and Architectures for QRD-Based Adaptive Signal Processing

(1993)

The least squares (LS) minimization problem constitutes the cores of many real-time signal processing problems, such as adaptive filtering, system identification and adaptive beamforming. Recently efficient implementations ...

#### Systolic Architectures for Signal Compression and Discrimination

(1994)

In this dissertation we propose systolic architectures for several classes of signal processing computations including schemes based on vector quantization and high order crossings techniques. The systolic concept is adapted ...

#### Exact, Recursive, Inference of Event Space Probability Law for Discrete Random Sets with Applications

(1991)

In this paper we extend Choquet's result to obtain a recursive procedure for the computation of the underlying event-space probability law for Discrete Random Sets, based on Choquet's capacity functional. This is an important ...

#### A Fully Parallel and Pipelined Systolic Array for MVDR Beamforming

(1991)

A fully-pipelined systolic array for computing the minimum variance distortionless response (MVDR) was first proposed by McWhirter and Shepherd. The fundamental concept is to fit the MVDR beamforming to the non-contrainted ...

#### Systolic Architectures for Finite-State Vector Quantization

(1991)

We present a new systolic architecture for implementing Finite State Vector Quantization in real-time for both speech and image data. This architecture is modular and has a very simple control flow. Only one processor is ...

#### VLSI Design of Discrete Fourier Transform Processors

(1991)

A bit-serial cell library is presented which can been used to rapidly implement discrete Fourier transform algorithms in VLSI circuit technology. The design methodology employs systolic summation arrays and multiplier ...

#### Novel Parallel Architectures for Short-Time Fourier Transform

(1992)

In this paper, novel parallel architectures for short-time Fourier transform based on adaptive time-recursive processing is proposed for efficient VLSI implementation. Only N - 1 multipliers and N + 1 adders are required. ...

#### Identification of Infinite Dimensional Systems Via Adaptive Wavelet Neural Networks

(1993)

We consider identification of distributed systems via adaptive wavelet neural networks (AWNNs). We take advantage of the multiresolution property of wavelet systems and the computational structure of neural networks to ...

#### Bayesian Hypothesis Testing for Boolean Random Sets with Radial Convex Primary Grains Using Morphological Skeleton Transforms

(1991)

We consider the problem of binary hypothesis testing for planar Boolean random sets with radial convex primary grains. We show that this problem is equivalent to the problem of binary hypothesis testing for Poisson points ...

#### Image Deconvolution Using Multiple Sensors

(1990)

We consider the two dimensional Analytic Bezout Equation (ABE) and investigate the properties of a particular solution, based on certain conditions imposed on the convolution kernels. We use a family of suitably chosen ...
