An Architectural Framework for VLSI Time-Recursive Computation with Applications
(1993)
The time-recursive computation model has been proven as a particularly useful tool in audio, video, radar and sonar real- time data processing architectures. Unlike the FFT based architectures, the time-recursive ones ...
Dynamic Range, Stability, and Fault-tolerant Capability of Finite-precision RLS Systolic Array Based on Givens Rotations
(1990)
The QRD RLS algorithm is generally recognized as having good numerical properties under finite-precision implementation. Also, it is very suitable for VLSI implementation since it can be easily mapped onto a systolic array. ...
A Unified Approach for Dyadic Shift Invariance and Cyclic Shift Invariance
(1991)
In this paper, the concept of the dyadic shift invariance (DSI) and cyclic shift invariant (CSI) functions are proposed. First, basic properties of the DSI and CSI functions are presented. Then, we can show that the ...
Bayesian Change Detection
(1991)
In this thesis we consider certain problems of optimal change detection in which the task is to decide in a sequential manner which of two probabilistic system descriptions account for given, observed data. Optimal decisions ...
Estimation of Multiple Sinusoidal Frequencies Using Truncated Least-Squares Methods
(1991)
Tufts and Kumaresan (1982) first proposed using a SVD-based method to solve the forward-backward linear prediction (FBLP) least-squares problem for resolving closely spaced frequencies of multiple sinusoids from limited ...
Adaptive Array Systems Using QR-Based RLS and CRLS Techniques with Systolic Array Architectures
(1991)
In this dissertation the basic techniques for designing more sophisticated adaptive array systems are first developed. Then several systolic architectures based on numerically stable and computationally efficient algorithms ...
Structure of Divisible Discrete Random Sets and Their Randomized Superpositions
(1991)
In this paper, we present an axiomatic formulation of Discrete Random Sets, and extend Choquet's uniqueness result to obtain a recursive procedure for the computation of the underlying event- space probability law, given ...
Optimal Unified Architectures for the Real-Time Computation of Time-Recursive Discrete Sinusoidal Transforms
(1993)
An optimal unified architecture that can efficiently compute the Discrete Cosine, Sine, Hartley, Fourier, Lapped Orthogonal, and Complex Lapped transforms for a continuous input data stream is proposed. This structure uses ...
Design and Implementation of Systolic Architectures for Vector Quantization
(1992)
Vector Quantization has emerged as an efficient data compression tool for compressing speech and image data. We develop efficient systolic architecture implementations of Tree-Search Vector Quantizers (TSVQ) and Finite-State ...
Analysis and Synthesis of Distributed Systems
(1994)
We first model and analyze distributed systems including distributed sensors and actuators. We then consider identification of distributed systems via adaptive wavelet neural networks (AWNNs) by taking advantage of the ...
