Impact of CSI on Distributed Space-Time Coding in Wireless Relay Networks
We consider a two-hop wireless network where a transmitter communicates with a receiver via M relays with an amplify-and-forward (AF) protocol. Recent works have shown that sophis...

Energy-efficient graph-based wavelets for distributed coding in Wireless Sensor Networks
This work presents a class of unidirectional lifting-based wavelet transforms for an arbitrary communication graph in a wireless sensor network. These transforms are unidirectiona...

Efficient Image and Channel Coding for Wireless Packet Networks
We combine multiple description (MD) quantization, entropy coding, and data partitioning to improve the error resiliency of images over varying packet loss channels. Our proposed ...

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...
