This work considers the design of a multi-stage vector quantizer (MSVQ) for application to the motion compensated prediction error of video signals. It is well known that the design of predictive vector quantizers suffers from fundamental difficulties due to the prediction loop, which have an impact on the convergence and the stability of the design procedure. We propose an approach to predictive MSVQ design that enjoys the stability of open-loop design while ensuring ultimate optimization of the closed-loop system. The proposed design method is tested on video compression at low bit rates, where it significantly outperforms widely-used closed-loop design techniques, and achieves improvement over the H.263 standard.

This paper proposes a bandwidth-scalable coding scheme based on the G.729 standard as a base layer coder. In the scheme, according to the channel conditions, the output speech of the decoder can be selected to be narrowband (4-kHz bandwidth) or wideband (8-kHz bandwidth). The proposed scheme consists of two layers: base and enhancement. The base coder uses the G.729 algorithm to encode narrowband speech. The enhancement coder is based on a full-band CELP model and it encodes wideband speech while making use of the available base layer information. Two bandwidth-scalable coders are designed: one is scalable with the 8 kbit/s G.729 base coder and another with the 6.4 kbit/s G.729 (Annex D) base coder. Subjective tests show that, for wideband speech, the proposed coders at 16 kbit/s achieve better performance than the 16 kbit/s MPEG-4 CELP with bandwidth scalability.

The design of a source-channel system based on the multi-stage vector quantizer (MSVQ) is optimized for packet networks. Resilience to packet loss is further enhanced by a proposed interleaving scheme that ensures that a single lost packet only eliminates a subset of the vector stages. The design is optimized while taking into account compression efficiency, packet loss rate, and the interleaving technique in use. Simulation results demonstrate that the packet network-optimized MSVQ outperforms traditional MSVQ for a variety of images and channel conditions, with gains of up to 2.0 dB in PSNR. Although the formulation is given in the context of packet networks, the work is directly extendible to the broader category of erasure channels.

This paper presents an in-depth study of classification of transients in power systems using two pattern classification methods, namely the maximum-likelihood, and the probabilistic neural networks. These methods, which stem from the Bayes rule, aim at estimating the underlying probability density functions that are required by the Bayes rule, but are often unavailable readily. The paper presents the mathematical foundations of classification using these two methods, followed by their implementation for classification of three types of transients, namely three-phase faults, breaker operations and capacitor switchings. Features used in this study are obtained using the wavelet and multifractal analyses of transient waveforms

This paper presents a block coding scheme based on a new construction of block-circulant Hadamard matrices. We describe this unified construction of Hadamard matrices of order 2/sup t/p where p is any odd number and t/spl ges/4 (depends on p), explaining how the block-circulant structure of the matrices contributes to more efficient coding. We introduce HC codes that can be implemented in software with relatively short encoding and decoding times. An HC matrix is compact in that it can be represented in its entirety by its first 2/sup t-1/ rows. Experiments show that the HC(64,7,32) code is better than the BCH(63,7,31) code by 1.5 dB and 2.8 dB over the corresponding uncoded data at SNR of 3 dB.

This paper presents a high quality enhanced waveform interpolative (EWI) speech coder at 2.8 kbps. The system incorporates novel features such as: dual-predictive analysis-by-synthesis (AbS) quantization of the slowly evolving waveform (SEW), efficient parametrization of the rapidly evolving waveform (REW) magnitude, and AbS vector quantization (VQ) of the REW parameter. Subjective tests indicate that its quality exceeds that of G.723.1 at 5.3 kbps, and it is slightly better than that of G.723.1 at 6.3 kbps.

This paper presents a study of a method for feature extraction and classification of voltage disturbances based on multifractal analysis of a voltage waveform with a transient. In this work, the variance fractal dimension trajectory is used to characterize a transient and to extract its features. The features extracted are a trajectory of fractal dimensions that are calculated over a number of overlapping windows along the transient signal. Based on their extracted features, classification of the transients is carried out using a statistical maximum likelihood classifier, which discriminates between three classes of voltage disturbances such as faults, breaker operations and capacitor switchings. The performance of the classifier is considered with both raw signals and also signals contaminated by noise.

The design of predictive quantizers generally suffers from difficulties due to the prediction loop, which have an impact on the convergence and the stability of the design procedure. We previously proposed an asymptotically closed-loop approach to quantizer design for predictive coding applications, which benefits from the stability of open-loop design while asymptotically optimizing the actual closed-loop system. In this paper, we present an enhancement to the approach where joint optimization of both predictor and quantizer is performed within the asymptotically closed-loop framework. The proposed design method is tested on synthetic sources (first-order Gauss and Laplacian-Markov sequences), and on natural sources, in particular, line spectral frequency parameters of speech signals.

This paper presents an enhanced waveform interpolative (EWI) speech coder at 4 kbps. The system incorporates novel features such as analysis-by-synthesis (AbS) vector-quantization (VQ) of the dispersion-phase, AbS optimization of the slowly evolving waveform (SEW), a special pitch search for transitions, and switched-predictive analysis-by-synthesis gain VQ. Subjective quality tests indicate that it exceeds that of MPEG-4 at 4 kbps and of G.723.1 at 5.3 kbps, and it is slightly better than that of G.723.1 at 6.3 kbps.
