Multiwindow method for spectrum estimation and sinusoid detection in an array environment
Multiwindow method for spectrum estimation and sinusoid dete...

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

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

advanced signal processing algorithms, architectures, and implementations II
作者: Williams, William J. Brown, Mark L. Hero III, Alfred O. Univ. of Michigan Ann Arbor MI USA
The well-known uncertainty principle is often invoked in signal processing. It is also often considered to have the same implications in signal analysis as does the uncertainty principle in quantum mechanics. The unce... 详细信息

作者: Games, Richard A. Eastman, Willard L. Sousa, Michael J. MITRE Corp. Bedford MA USA
This paper describes an efficient implementation of auxiliary constraints for a concurrent block least squares adaptive sidelobe canceller when a single array of sensors is used to form one or more main beams. The app... 详细信息

advanced signal processing algorithms, architectures, and implementations II
作者: Carmona, Edward A. Matson, Charles L. U.S. Air Force/Phillips Lab. Kirtland AFB NM USA
We compare the performance of three parallel supercomputers executing a bispectrum estimation code used to remove distortions from astronomical data. We discuss the issues in parallelizing the code on an 8-processor s... 详细信息

作者: Chen, Wei G. Reilly, James P. Wong, Kon M. McMaster Univ. Hamilton Ontario Canada
A new approach to the problem of detecting the number of signals in unknown colored noise environments is presented. Based on an assumption that the noise is correlated only over a limited spatial range, the principle... 详细信息

作者: Ku, Ta-Kang Kuo, C.-C.J. Univ. of Southern California Los Angeles CA USA
A new preconditioner is proposed for the solution of an N × N Toeplitz system TNx = b, where TN can be symmetric indefinite or nonsymmetric, by preconditioned iterative methods. The preconditioner FN is obtained ... 详细信息
