SPIE Conference on advanced signal processing algorithms, architectures, and implementations VIII
作者: Yao, K Hudson, RE Reed, CW Chen, D Tung, TL Lorenzelli, F Univ Calif Los Angeles Dept Elect Engn Los Angeles CA 90095 USA
We briefly review the signal processing architecture of a wireless MEM sensor system for source detection, signal enhancement, localization, and identification. A blind beamformer using only the measured data of rando... 详细信息

IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS II-ANALOG AND DIGITAL signal processing 1998年 第7期45卷 821-838页
作者: Denk, TC Parhi, KK Lucent Technol Bell Labs Holmdel NJ 07733 USA Univ Minnesota Dept Elect & Comp Engn Minneapolis MN 55455 USA
Scheduling and retiming are important techniques used in the design of hardware and software implementations of digital signal processing algorithms. In this paper, techniques are developed for generating all scheduli... 详细信息

SPIE Conference on advanced signal processing algorithms, architectures, and implementations VIII
作者: Nelson, DJ Kenny, OP US Dept Def Ft George G Meade MD 20755 USA
In this paper, we present a new class of representations of signals in the time-frequency (TF) plane. These representations are complex valued, linear, and satisfy reconstruction conditions in which the signal and its... 详细信息

SPIE Conference on advanced signal processing algorithms, architectures, and implementations VIII
作者: Smith, D Townsend, J Nelson, DJ US Dept Def Ft George G Meade MD 20755 USA
Computationally efficient algorithms which perform speech activity detection have significant potential economic and labor saving benefit, by automating an extremely tedious manual process. In many applications, it is... 详细信息

SPIE Conference on advanced signal processing algorithms, architectures, and implementations VIII
作者: Chu, MT Funderlic, RE Plemmons, RJ N Carolina State Univ Dept Math Raleigh NC 27695 USA
We consider two general procedures for constructing the nearest approximation of a given matrix by one with any lower rank and any linear structure. Nearness can be measured in any matrix norm. Structured low rank mat... 详细信息

SPIE Conference on advanced signal processing algorithms, architectures, and implementations VIII
作者: Ma, J Parhi, KK Hekstra, GJ Deprettere, EF Univ Minnesota Dept ECE Minneapolis MN 55455 USA
CORDIC based IIR digital filters are orthogonal filters whose internal computations consist of orthogonal transformations. These filters possess desirable properties for VLSI implementations such as regularity, local ... 详细信息

SPIE Conference on advanced signal processing algorithms, architectures, and implementations VIII
作者: Nickel, RM Williams, WJ Univ Michigan Dept Elect Engn & Comp Sci Ann Arbor MI 48109 USA
One of the key problems in high resolution (quadratic), time-varying spectral analysis is the suppression of interference terms which can obscure the true location of auto components in the resulting time-frequency di... 详细信息
