Two-way source coding with a helper
Consider the two-way rate-distortion problem in which a helper sends a common limited-rate message to both users based on side information at its disposal. We characterize the reg...

Globally Optimal Uneven Erasure-Protected Multi-Group Packetization of Scalable Codes
We study the problem of rate-distortion optimal packetization with uneven erasure protection (UEP) of scalable source sequence, into multiple groups of packets. The grouping of pa...

Source-Channel Communication in Sensor Networks
Sensors acquire data, and communicate this to an interested party. The arising coding problem is often split into two parts: First, the sensors compress their respective acquired s...
