On the distortion exponents of layered broadcast transmission in multi-relay cooperative networks
In this paper, we consider the transmission of a Gaussian source over a cooperative relay network, and analyze its end-to-end distortion at high signal-to-noise ratio, in terms of ...

Joint Source-Channel Decoding of Multiple Description Quantized Markov Sequences
This paper proposes a framework for joint source-channel decoding of Markov sequences that are coded by a fixed-rate multiple description quantizer (MDQ), and transmitted via a lo...

Message and State Cooperation in a Relay Channel When the Relay Has Strictly Causal State Information
—A state-dependent relay channel is studied in which strictly causal channel state information is available at the relay and no state information is available at the source and d...

Frame permutation quantization
—Frame permutation quantization (FPQ) is a new vector quantization technique using finite frames. In FPQ, a vector is encoded using a permutation source code to quantize its fra...
