Approximate Characterizations for the Gaussian Source Broadcast Distortion Region
We consider the joint source-channel coding problem of sending a Gaussian source over a K-user Gaussian broadcast channel with bandwidth mismatch. A new outer bound to the achieva...

Diversity Embedded Streaming Erasure Codes (DE-SCo): Constructions and Optimality
Streaming erasure codes encode a source stream to guarantee that each source packet is recovered within a fixed delay at the receiver over a burst-erasure channel. This paper intro...
