conference on advanced signal processing - algorithms, architectures, and implementations viI
作者: ONeill, JC Ecole Normale Superieure de Lyon (United States)
In time-frequency analysis, we extend functions of one variable to functions of two variables. The functions of two variables provide information about the signal that is not easily discernible from the functions of o... 详细信息

conference on advanced signal processing - algorithms, architectures, and implementations viI
作者: Paul, S Gotze, J Institute for NTCD TU Munich D-80290 Munich Germany
The Jacobi method for singular value decomposition is well-suited for parallel architectures. Its application to signal subspace computations is well known. Basically the subspace spanned by singular vectors of large ... 详细信息

conference on advanced signal processing - algorithms, architectures, and implementations viI
作者: Crouse, MS Nowak, RD Mhirsi, K Baraniuk, RG Rice Univ. (United States) Michigan State Univ. (United States)
This paper addresses the problem of detection and classification of complicated signals in noise. Classical detection methods such as energy detectors and linear discriminant analysis do not perform well in many situa... 详细信息

conference on advanced signal processing - algorithms, architectures, and implementations viI
作者: Pitton, JW MathSoft Seattle WA 98109 1700 Westlake Ave N United States
An algorithm for computing positive time-frequency distributions (TFDs) for nonstationary signals is presented. This work extends the earlier work of the author and his colleagues in computing positive TFDs [11, 15]. ... 详细信息

conference on advanced signal processing - algorithms, architectures, and implementations viI
作者: Sarajedini, A Chau, PM Univ. of California/San Diego (United States)
Spread spectrum modulation techniques such as frequency-hopped code division multiple access (FH-CDMA) are an efficient way to allow multi-user transmission over a limited bandwidth. Recently, there has been a push to... 详细信息

conference on advanced signal processing - algorithms, architectures, and implementations viI
作者: Belouchrani, A Amin, MG Villanova Univ. (United States)
Blind source separation is an emerging field of fundamental research with a broad range of applications. It is motivated by practical problems that involve several source signals and several sensors. Each sensor recei... 详细信息

conference on advanced signal processing - algorithms, architectures, and implementations viI
作者: Loughlin, PJ Univ. of Pittsburgh (United States)
We consider the definition and interpretation of instantaneous frequency and other time-varying frequencies of a signal, and related concepts of instantaneous amplitude, instantaneous bandwidth and the time-varying sp... 详细信息

conference on advanced signal processing - algorithms, architectures, and implementations viI
作者: Winograd, JM Nawab, SH Boston Univ. (United States)
A new architecture is presented for incremental computation of the two-dimensional inverse discrete cosine transform (2D-IDCT) in the context of progressive image decoding. This architecture offers advantages over exi... 详细信息
