Energy-aware noise reduction for wireless acoustic sensor networks

In speech processing applications, e.g., speech recognition, hearing aids (HAs), video conferencing, and human-computer interaction, speech enhancement or noise reduction is an essential front-end task, as the recorded speech signals are inevitably corrupted by interference, including coherent/incoherent noise and reverberation. Traditional...

Multi Bit-Rate Video on Demand for P2P networks

The Internet has become in the last years more and more a means of conveyance for multimedia delivering. Many solutions have been proposed to gain high quality of service for video on demand in client-server environments, with adaptive algorithms that adjust the bit-rate of a video stream depending on the clients available bandwidth. Providing...

Data Broadcasting in HIPERLAN: Design and Testing of a High Data Rate Protocol with Feedback in a Wireless LAN

A new protocol for transmitting the same data to several user-stations on a broadcast medium has been designed. It uses a regular HIPERLAN (High Performance Radio Local Area Network) protocol to broadcast the data. The difference between the new protocol and the regular HIPERLAN protocol is, that the new protocol provides a transport service...
