Digital Signal Processing for Audio and Telecommunications

To face the increasing demand for communication services, new (e.g. wireless) communication networks are currently being installed and existing (e.g. wireline) networks are being upgraded. Optimal performance in such networks is obtained with novel high-speed modems, where advanced digital signal processing (DSP) techniques are an indispensable and crucial new ingredient. The research on DSP algorithms for Digital Communications reported here aims at the development of equalization, multiple-access (SDMA, CDMA), echo and interference cancellation techniques for high-speed telephone line modems (ADSL/VDSL), cable modems, and wireless communication. Audio signal processing activities are targeted towards speech communications, conferencing, voice-control, and hearing aid applications. Multi-microphone signal enhancement, dereverberation, acoustic echo cancellation, and feedback cancellation are current points of focus. Hearing aid and cochlear implant work is performed in co-operation with Prof. J. Wouters, Lab. Exp. O.R.L., K.U.Leuven.
