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 ...
Ripple Analysis in Ferret Primary Auditory Cortex. II. Topographic and Columnar Distribution of Ripple Response Parameters
(1994)
We examined the columnar and topographic distribution of response parameters using spectral ripples and tonal stimuli in the primary auditory cortex (AI) of the barbiturate-anesthetized ferret. The ripple stimuli consisted ...
Conditions for the Equivalence of ARMAX and ARX Systems
(1991)
It is shown that an autoregressive moving average with exogenous input (ARMAX) system can be represented as an autoregressive with exogenous input (ARX) model if and only if the transfer function from the noise port to the ...
Convergence Analysis of a Class of Networks of Nonlinear Coupled Oscillators
(1994)
A network of nonlinear coupled oscillators is presented, and a convergence proof is given along with physical motivation. Next, the network architecture is generalized by allowing interconnections between oscillators to ...
Blind MIMO FIR Channel Identification Based on Second-Order Statistics with Multiple Signals Recovery
(1996)
To separate and recover multiple signals in data communications, antenna arrays and acoustic sensor arrays, the impulse responses of multiple-input/multiple-output (MIMO) channels have to be identified explicitly or ...
Representation of Spectral Profiles in the Auditory System Part II: A Ripple Analysis Model
(1993)
Based on experimental results presented in [Vranic-Sowers and Shamma, 1993], and on further physiological and psychoacoustical evidence, it is argued that the auditory system analyzes a spectral profile along two largely ...
An ESPRIT Algorithm for Tracking Time-Varying Signals
(1992)
ESPRIT is a successful algorithm for determining the constant directions of arrival of a set of narrowband signals on an array of sensors. Unfortunately, its computational burden makes it unsuitable for real time processing ...
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 ...
