the aim of this paper is to improve the performance of the conventional goertzel algorithm in determining the protein codingregions in deoxyribonucleic acid (dna) sequences. first, the symbolic dna sequences are converted into numerical signals usingelectron ion interaction potential method. then by combining the modified anti-notch filter and linear predictive coding model,we proposed an effic...

Abstract In this paper, we present a method of estimating the volatility of a signal that displays stochastic noise (such as a risky asset traded on an open market) utilizing Linear Predictive Coding. The main purpose is to associate volatility with a series of statistical properties that can lead us, through further investigation, toward a better understanding of structural volatility as well ...

The paper presents a novel technique for underwater acoustic voice communications. The speech signal is compressed prior to transmission by using Linear Predictive Coding and transmission of appropriate speech parameters is achieved by Digital Pulse Position Modulation. The main emphasis here is on the reception of the multipath-dominant signal and on the demodulation process.

This paper addresses the problem of reconstructing wideband speech signals from observed narrowband speech signals. The goal of this work is to improve the perceived quality of speech signals which have been transmitted through narrowband channels or degraded during acquisition. We describe a system, based on linear predictive coding, for estimating wideband speech from narrowband. This system ...

Frequency-warped signal processing techniques are attractive to many wideband speech and audio applications since they have a clear connection to the frequency resolution of human hearing. A warped version of linear predictive coding (LPC) is studied in this paper. The performance of conventional and warped LPC algorithms are compared in a simulated coding system using listening tests and conve...

This paper presents a statistical multipich analyzer based on a source-filter model that decomposes a target music audio signal in terms of three major kinds of sound quantities: pitch (fundamental frequency: F0), timbre (spectral envelope), and intensity (amplitude). If the spectral envelope of an isolated sound is represented by an all-pole filter, linear predictive coding (LPC) can be used f...
