Abstract :
In this paper delay-free distributed joint source-channel coding for communication of two correlated Gaussian sources over a Gaussian Multiple Access Channel (GMAC) are considered. Both discrete and hybrid discrete analog schemes are proposed and optimized. The proposed schemes are noise robust and show promising performance which improve with increasing correlation.
