Abstract

This paper presents research results involving the development of a speech enhancement algorithm for wireless communication systems. The algorithm has also been designed to be amenable to real-time processing on Texas Instrument´s TMS320C3X digital signal processing (DSP) chip. The algorithm uses adaptive single-channel correlation, or higher order cumulants, to achieve its goal of noise reduction. The algorithm has been tested using the CTIMIT data base. The paper presents some quantitative results and outlines some subjective assessments that we intend to perform in our continuation of this research.
