IEE PROCEEDINGS-COMMUNICATIONS 2004年 第1期151卷 32-38页
作者: Fu, H Attallah, S Inst Infocomm Res Singapore 119613 Singapore Curtin Univ Technol Bentley WA 6102 Australia
The problem of CDMA multiuser detection in the presence of a small residual carrier offset is considered, with subspace-based approaches being employed for channel estimation and signal demodulation. The channel respo... 详细信息

INTERNATIONAL JOURNAL OF PLASTICITY 2004年 第8-9期20卷 1403-1440页
作者: Harth, T Schwan, S Lehn, J Kollmann, FG Tech Univ Darmstadt Dept Math D-64289 Darmstadt Germany
In this paper we introduce stochastic methods to describe the influence of scattering test data on the identification of material parameters. We employ the viscoplastic constitutive model of Chan, Bodner, and Lindholm... 详细信息
