A new analysis-by-synthesis speech coding structure is presented for high-quality speech coding in the 4 to 8 kb/s range. CELP with generalized pitch prediction (GPP-CELP) di ers from classical code-excited linear prediction (CELP) in that for voiced segments it is the speech signal that is decomposed into a component predictable with the aid of the adaptive codebook (ACB) and a nonpredictable ...

technical analysis is the forecasting of future price movement based on an examination of past prices. some scientist found that the study of historical prices cannot predict future prices. in this research we intend to study which technical analysis tool is better for prediction of future price movement, for this purpose we are studying two the most strongest technical analysis tools is called...

Piston engines fueled by kerosene have a strong application prospect in special vehicles and small aircrafts, but the low amount of octane fuel causes its knock combustion phenomenon to be particularly serious. A will deteriorate power economy engine damage serious cases. Therefore, knocking is key problem with engines. We propose knock-prediction system for based on in-cylinder pressure signal...

A new approach for multiple description video coding using motion compensated prediction is proposed. The temporal predictor is designed to provide a desired trade-off between prediction gain and mismatch between the predictions obtained at the encoder and that at the decoder when only one description is available. The mismatch signal is explicitly coded to avoid error propagation. The system c...

This paper develops two new adaptive wavelet transforms based on the lifting scheme. The lifting construction exploits a spatialdomain, prediction-error interpretation of the wavelet transform and provides a powerful framework for designing customized transforms. We use the lifting construction to adaptively tune a wavelet transform to a desired signal by optimizing data-based prediction error ...

A new frequency estimator for a single complex sinusoid in complex white Gaussian noise is proposed. The estimator is more computationally efficient than the optimal maximum likelihood estimator yet attains as good performance at moderately high signal-tonoise ratios. Also, the estimator is shown to be related to the linear prediction estimator. This relationship is exploited to reveal why the ...

This paper presents a frequency weighted generalized total least squares linear prediction for estimating closely spaced sinusoids. In this method, the received data is first processed by a pole-zero prefilter and then a generalized total least squares linear prediction is applied to the prefiltered signal. A procedure of optimizing the generalized solution is introduced. By computer simulation...
