Optimal packetization of VLC and convolution coded Markov sequences
We consider the problem of packetizing a variable length coded Markov sequence into fixed length packets, while being protected by variable rate channel code. Given the total tra...

Globally Optimal Uneven Error-Protected Packetization of Scalable Code Streams
In this paper, we present a family of new algorithms for rate-fidelity optimal packetization of scalable source bit streams with uneven error protection. In the most general settin...

Optimized Rate Allocation for Unbalanced Multiple Description Video Coding Over Unreliable Packet Network
Video transmission over unreliable packet network is in general hampered by the packet losses and constraint by stringent playback deadline. With these two key factors in consider...

Adaptive Compress-and-Forward Relaying in Fading Environments with or without Wyner-Ziv Coding
Abstract--Compress-and-Forward is a protocol for transmission over relay networks in which the relay forwards a compressed version of the signal it observes. The compression method...
