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

SPIE conference on advanced signal processing algorithms, architectures, and implementations viII
作者: Kilmer, ME Northeastern Univ Dept Elect & Comp Engn Boston MA 02115 USA
In certain applications, the discretization of two-dimensional integral equations can lead to systems involving matrices with block Toeplitz-Toeplitz block structure. Iterative Krylov subspace methods are sometimes em... 详细信息

作者: Rajagopalan, R Pratt & Whitney Control & Diagnost Syst Propul Syst Anal E Hartford CT 06108 USA
Moving average filters are commonly used in industries for real-time processing of noisy data. Though they perform well in filtering out the noise, they introduce significant lag in the signal. The resulting peak valu... 详细信息

作者: Clark, Pascal Atlas, Les Univ Washington Dept Elect Engn Seattle WA 98195 USA
Modulation filtering is a technique for filtering slowly-varying envelopes of frequency subbands of a non-stationary signal, ideally without affecting the signal's phase and fine-structure. Coherent modulation fil... 详细信息
