Proceedings of the 1999 advanced signal processing algorithms, architectures, and implementations IX
作者: Bonato, Paolo Erim, Zeynep Roy, Serge H. De Luca, Carlo J. Boston Univ Boston United States
The aim of this work is to contrast techniques used to estimate two instantaneous frequency parameters of the surface electromyographic (EMG) signal, the instantaneous median frequency and the instantaneous mean frequ... 详细信息

advanced signal processing: algorithms, architectures, and implementations V
作者: Tugnait, Jitendra K. Gummadavelli, Uma Auburn Univ. Auburn AL USA
Existing approaches to blind channel estimation and deconvolution (equalization) focus exclusively on channel or inverse-channel impulse response estimation. It is well-known that the quality of the deconvolved output... 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
