Watermark Synchronization for Feature-Based Embedding: Application to Speech
We propose a novel framework for synchronization in feature-based data embedding systems. The framework is tolerant to de-synchronizing errors in feature estimates, which have hit...

Adaptive precoding for downstream crosstalk precancelation in DSL systems using sign-error feedback
The performance of many very high bit rate digital subscriber line (VDSL) systems is limited by the effects of crosstalk among the wires in a bundle. For the downstream, a precoder...

Using H.264/AVC-based Scalable Video Coding (SVC) for Real Time Streaming in Wireless IP Networks
— A streaming system based on the Scalable Video Coding (SVC) extension of H.264/AVC is shown. SVC allows for data rate adaptation without re-encoding just by dropping packets of...
