6th International Conference on Information Technology and Multimedia (ICIM)
作者: Javed, Shazia Ahmad, Noor Atinah Univ Sains Malaysia Sch Math Sci George Town 11800 Malaysia
In this paper, an instantaneous total error based adaptive linear predictor is presented for linear predictive coding (LPC) of speech signals. In LPC, the speech signal is predicted by a linear combination of delayed ... 详细信息

9th Annual Conference of the International-Speech-Communication-Association (INTERSPEECH 2008)
作者: Gournay, Philippe Univ Sherbrooke Speech & Audio Res Grp Sherbrooke PQ J1K 2R1 Canada
In CELP coders, the past excitation signal used to build the adaptive codebook is known to be the main source of error propagation when a frame is lost. This paper presents a novel resynchronization technique using ve... 详细信息

46th Asilomar Conference on Signals, Systems and Computers
作者: Barrenechea, Maitane Burg, Andreas Mendicute, Mikel Univ Mondragon Dept Elect & Comp Sci Arrasate Mondragon 20500 Spain Ecole Polytech Fed Lausanne Inst Elect Engn CH-1015 Lausanne Switzerland
Vector precoding enables non-cooperative signal acquisition in the multi-user broadcast channel. The performance advantage with respect to the more straightforward linear precoding algorithms comes as a consequence of... 详细信息

IEEE International Conference on Image Processing (ICIP 2007)
作者: Moorer, James A. Adobe Syst Inc San Jose CA 95110 USA
The CD revolution of 1984 unleashed a massive campaign of rerelease of vintage analog recordings. To their collective horror, record labels found that many of the original master recordings had deteriorated. Often the... 详细信息

International Conference on Control, Artificial Intelligence, Robotics & Optimization (ICCAIRO)
作者: Struwe, Kevin Univ Rostock Inst Appl Microelect & Comp Engn D-18051 Rostock Germany
Voiced-Unvoiced classification (V-UV) is a well understood but still not perfectly solved problem. It tackles the problem of determining whether a signal frame contains harmonic content or not. This paper presents a n... 详细信息

IEEE International Conference on Acoustics, Speech, and Signal Processing
作者: Nordén, F Hedelin, P Chalmers Univ Technol Informat Theory Lab SE-41296 Gothenburg Sweden
Low-complexity scalable methods are of importance to achieve multi-rate and variable rate speech coding. Adopting the CELP concept, we focus on the innovation coding, suggesting an adaptive companding VQ. We present a... 详细信息

3rd IEEE Global Conference on Signal and Information Processing (GlobalSIP)
作者: Kamamoto, Yutaka Moriya, Takehiro Harada, Noboru NTT Corp NTT Commun Sci Labs Atsugi Kanagawa Japan
Lag windowing has long been used for the auto-correlation method of linear predictive (LP) analysis to prevent possible instability of the synthesis filter with the obtained coefficients. We have investigated the lag-... 详细信息
