Instantaneous bandwidth of multicomponent signals
Instantaneous bandwidth of multicomponent signals

Proceedings of the 1999 advanced signal processing algorithms, architectures, and implementations IX
作者: Loughlin, Patrick J. Davidson, Keith L. Univ of Pittsburgh Pittsburgh United States
As with the case of instantaneous frequency, it is often difficult to interpret the instantaneous bandwidth of most signals: both quantities typically range beyond the spectral support of the signal, yielding the para... 详细信息

advanced signal-processing algorithms, architectures, and implementations
作者: Delosme, Jean-Marc Hsiao, Shen-Fu Yale Univ New Haven United States
CORDIC algorithms offer an attractive alternative to multiply-and-add based algorithms for the implementation of two-dimensional rotations, preserving either norm: (x2 + y2) 1/2 or (x2 - y2) 1/2 . Indeed these nor who... 详细信息

作者: Bojanczyk, Adam W. Ewerbring, L.Magnus Luk, Franklin T. Van Dooren, Paul Cornell Univ Ithaca United States
In this paper, we propose a new algorithm for computing a singular value decomposition of a matrix product. We show that our algorithm is numerically desirable in that all relevant residual elements will be numericall... 详细信息

advanced signal processing algorithms, architectures, and implementations II
作者: Abbiss, John B. Brames, Bryan J. Spectron Development Labs. Inc. Costa Mesa CA USA
We present an analysis and computational results relating to the regularized restoration of subpixel information from undersampled data. The method makes use of a small set of images in various stages of defocus. An i... 详细信息

advanced signal processing: algorithms, architectures, and implementations V
作者: Marinovich, Nenad M. CUNY/City Coll. and Graduate Sch. New York NY USA
An algorithm is proposed to compute samples of any bilinear joint time-frequency representation of the Cohen's class. The computation is performed on a decimated sampling grid, mapping N = 3BD signal samples into ... 详细信息

advanced signal processing algorithms, architectures, and implementations II
作者: McQuillan, S.E. McCanny, J.V. Queen's Univ. of Belfast Belfast Belfast United Kingdom
A high performance VLSI architecture to perform combined multiply-accumulate, divide, and square root operations is proposed. The circuit is highly regular, requires only minimal control, and can be pipelined right do... 详细信息

Proceedings of the 1999 advanced signal processing algorithms, architectures, and implementations IX
作者: Nelson, Douglas J. Wysocki, Wayne U.S. Dep of Defense Fort George G. Meade United States
We present a discussion of methods based on the complex cross-spectrum and the application of these methods to the analysis of speech. The cross spectral methods developed here are an extension of methods developed in... 详细信息

advanced signal processing algorithms, architectures, and implementations II
作者: Onn, Ruth Steinhardt, Allan O. Cornell Univ. Ithaca NY USA
In many applications (radar, communication, plasma physics) the signal of interest is sinusoidal and is hidden in non-white noise. The multi-window method of spectrum estimation gives a constant false alarm test for t... 详细信息

Conference on advanced signal processing algorithms, architectures, and implementations XI
作者: Rabinkin, DV Song, W Vai, MM Nguyen, H MIT Lincoln Lab Lexington MA 02420 USA
Adaptive array systems require the periodic solution of the well-known w = (R) over tilde (-1)v equation in order to compute optimum adaptive array weights. The covariance matrix (R) over tilde is estimated by forming... 详细信息
