Toward a unified framework for modeling and analysis of diversity in joint source-channel coding
The study of Joint Source-Channel Coding (JSCC) systems faces one major challenge in obtaining an analytical expression for the function that links end-to-end distortion with chann...

Hybrid Genetic Algorithm for Design of Robust Communication Systems
A novel hybrid genetic algorithm (GA) for jointly optimizing source and channel codes is presented in this paper. The algorithm first uses GA for the coarse search of source and ch...

DCC-MAC: A Decentralized MAC Protocol for 802.15.4a-like UWB Mobile Ad-Hoc Networks Based on Dynamic Channel Coding
We present a joint PHY/MAC architecture (DCC-MAC) for 802.15.4a-like networks based on PPM-UWB. Unlike traditional approaches it fully utilizes the specific nature of UWB to achie...
