Title: Samir Chennoukh: Innovator in Speech Signal Processing

Introduction

Samir Chennoukh is a notable inventor based in Eindhoven, Netherlands. He has made significant contributions to the field of speech signal processing, holding three patents that enhance the quality of audio transmission. His work focuses on improving the perceptual quality of telephone speech, which is crucial in today's communication landscape.

Latest Patents

Chennoukh's latest patents include "Wideband extension of telephone speech for higher perceptual quality." This invention describes a method for extending the frequency range of a speech signal using a wideband extension method with an inverse filter and a synthesis filter. Both filters receive LPC coefficients from an LPC estimator, allowing for the generation of wideband LPC coefficients from wideband LSFs. The wideband LSFs are created by appending highband LSFs and lowband LSFs, which are derived from narrowband LSFs.

Another significant patent is the "Wideband signal transmission system." This invention outlines a transmission system that includes a transmitter for sending a narrowband audio signal to a receiver via a transmission channel. The receiver features a frequency domain bandwidth extender that enhances the bandwidth of the received narrowband audio signal. This system is characterized by an amplitude extender and a phase extender, which work together to create a bandwidth-extended audio signal.
