International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: Axel Heim Uli Sorger Florian Hug Institute of Telecommunications and Applied Information Theory Ulm University Germany Computer Science and Communications University of Luxembourg Luxembourg
A common technique to deploy linear prediction to non-stationary signals is time segmentation and local analysis. Variations of a process within such a segment cause inaccuracies. In this paper, we model the temporal ... 详细信息
