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

Proceedings of the 1999 advanced signal processing algorithms, architectures, and implementations IX
作者: Ringelstein, J. Gershman, A.B. Boehme, J.F. Ruhr Univ Bochum Germany
The performances of high-resolution array processing methods are known to degrade in random inhomogeneous media because the amplitude and phase of each wavefront tend to fluctuate and to loose their coherence between ... 详细信息

Proceedings of the 1999 advanced signal processing algorithms, architectures, and implementations IX
作者: Tenca, Alexandre F. Ercegovac, Milos D. Louie, Marianne E. Oregon State Univ Corvallis United States
This paper presents the application of the Linear Sequential Array (LSA) retiming approach, developed for conventional digit-recurrence algorithms, to on-line multiplication. The result is a modular and fast pipelined... 详细信息

Proceedings of the 1999 advanced signal processing algorithms, architectures, and implementations IX
作者: Nickel, Robert M. Williams, William J. Univ of Michigan Ann Arbor United States
We are presenting a new class of transforms which facilitates the processing of signals that are nonlinearly stretched or compressed in time. We refer to nonlinear stretching and compression as warping. While the magn... 详细信息

作者: Zhang, Yimin Mu, Weifeng Amin, Moeness G. Villanova Univ Villanova United States
This paper proposes a novel time-frequency maximum likelihood (t-f ML) method for direction-of-arrival (DOA) estimation for non-stationary signals, and compares this method with conventional maximum likelihood DOA est... 详细信息

Proceedings of the 1999 advanced signal processing algorithms, architectures, and implementations IX
作者: Williams, William J. Aviyente, Selin Univ of Michigan Ann Arbor United States
This paper outlines means of using special sets of orthonormally related windows to realize Cohen's class of time-frequency distributions (TFDs). This is accomplished by decomposing the kernel of the distribution ... 详细信息

Proceedings of the 1999 advanced signal processing algorithms, architectures, and implementations IX
作者: Xu, Gang Cavallaro, Joseph R. Rice Univ Houston United States
The multistage detection algorithm has been widely accepted as an effective interference cancellation scheme for next generation Wideband Code Division Multiple Access (W-CDMA) base stations. In this paper, we propose... 详细信息
