Stable Behavior and Stabilizing Supervisor for Discrete Event Dynamical Systems
(1991)
The paper studies stability and stabilizability of Discrete event Dynamical Systems (DEDS's) in the framework of Ramadge and Wonham. We define stability and stabilizability in terms of the behavior of the DEDS's, i.e. the ...
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 ...
Dual-State Systolic Architectures for Adaptive Filtering Using Up/Downdating RLS
(1991)
We propose a dual-state systolic structure to perform joint up/down-dating operations encountered in windowed recursive least squares (RLS) estimation problems. It is derived by successively performing Givens rotations for ...
Parallel and Fully-Pinelined Instantaneous Optimal Weight Extraction for Adaptive Beamforming Using Systolic Arrays
(1991)
In this paper we present systolic algorithms and architectures for parallel and fully-pipelined instantaneous optimal weight extraction for multiple sidelobe canceller (MSC) and minimum variance distortionless response ...
Unified Parallel Lattice Structures for Time-Recursive Discrete Cosine/Sine/Hartley Transforms
(1991)
The problems of unified efficient computations of the discrete cosine transform (DCT), discrete sine transform (DST), discrete Hartley transform (DHT), and their inverse transforms are considered. In particular, a new ...
Multi-phase Systolic Algorithms for Spectral Decomposition
(1991)
In this paper, we propose two multi-phase systolic algorithms to solve the spectral decomposition problem based on the QR algorithm. The spectral decomposition is one of the most computationally intensive modern signal ...
