Latest Patents

Ghenania's latest patents include a "Method and device for carrying out optimal coding between two long-term prediction models." This invention discloses a system and method for implementing compression coding of audio signals, such as speech signals, using two long-term prediction (LTP) models. The method determines the parameters of a second long-term prediction model based on the parameters of at least one first LTP model. The invention aims to switch between LTP models with varying coefficients, allowing for adjustments in complexity based on desired quality and target complexity.

Another significant patent is the "Method for adapting for interoperability between short-term correlation models of digital signals." This invention relates to the code conversion of digital signals, particularly voice signals. It involves coding according to a second format from information obtained by coding according to a first format. The LPC coefficients of the second format are determined through dynamic interpolation of the representative values of the LPC coefficients from the first format.
