Linear Predictive Coding Of Myoelectric Signals

Proceedings. (ICASSP '05). IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005., 2006
Despite the great interest towards long term recordings of electromyographic (EMG) signals, which find applications, for example, in telemedicine, only a few studies have dealt with the compression of these signals. We propose a lossy coding technique for surface EMG signals.

Linear predictive coding for sonar data

2017 IEEE Global Conference on Signal and Information Processing (GlobalSIP), 2017
Sonar is commonly used in the underwater environment for navigation and obstacle detection. The large volume of data, generated by an array of acoustical sensors, has to be transmitted and stored, giving a great motivation for applying compression methods.

Warped linear predictive speech coding

2011 IEEE International Conference on Signal and Image Processing Applications (ICSIPA), 2011
This project aims to enhance human speech energy at low frequencies using linear prediction methods to achieve better performance for speech recognizers in noisy conditions. In order to achieve this, a recognition system based on Warped Linear Prediction (WLP) is proposed.

Piecewise linear predictive coding (PLPC)

ICASSP '76. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
A great deal of current research in the area of narrowband digital speech compression makes use of the Linear Prediction Coding (LPC) algorithm to extract the vocal track spectrum. This paper describes a technique that splits the spectrum into two equal halves and performs a piecewise LPC approximation to each half. By taking advantage of the classical

SPEECH CODING WITH LINEAR PREDICTIVE CODING

Mechanical and Electronics Engineering, 2009
Speech coding has been and still is a major issue in the area of digital speech processing in which speech compression is needed for storing digital voice and it requires fixed amount of available memory and compression makes it possible to store longer messages.

A comparison of warped and conventional linear predictive coding

IEEE Transactions on Speech and Audio Processing, 2001
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.
