2nd ieee sensor array and multichannel signal processing workshop
作者: Krasny, L Oraintara, S Ericsson Inc Res Triangle Pk NC USA
This paper describes the use of voice activity defector (VAD) in microphone array processing for hand-free systems. Two different types of VAD are proposed using conventional and adaptive beamforming. Taking into acco... 详细信息

3rd ieee sensor array and multichannel signal processing workshop
作者: Aouada, R Belouchrani, A Abed-Meraim, K ENP Elect Engn Dept Algiers Algeria
We consider the problem of estimating the parameters of linear chirp signals when received at a multi-sensor antenna. Exploiting the negligible variation of the parameters of interest over the coherence time of the ch... 详细信息

ieee 7th sensor array and multichannel signal processing workshop (SAM)
作者: Zhang, Yimin D. Amin, Moeness G. Villanova Univ Ctr Adv Commun Villanova PA 19085 USA
Compressive sensing (CS) has successfully been applied to reconstruct sparse signals and images from few observations. For multi-component nonstationary signals characterized by instantaneous frequency laws, the spars... 详细信息

ieee 12th sensor array and multichannel signal processing workshop (SAM)
作者: Huang, Huiping So, Hing Cheung Zoubir, Abdelhak M. Tech Univ Darmstadt Darmstadt Germany City Univ Hong Kong Hong Kong Peoples R China
In this paper, we devise a sparse array design algorithm for adaptive beamforming. Our strategy is based on finding a sparse beamformer weight to maximize the output signal-tointerference-plus-noise ratio (SINR). The ... 详细信息

1st ieee sensor array and multichannel signal processing workshop (SAM 2000)
作者: Zatman, M MIT Lincoln Lab Lexington MA 02420 USA
Most adaptive array processing schemes assume that the interference is 'wide sense stationary'. However, in practice this assumption is often violated. For example there may be motion of either the array and/o... 详细信息
