Asymptotically Optimal Joint Source-Channel Coding with Minimal Delay
arXiv:0904.1281 · doi:10.1109/GLOCOM.2009.5425427
Abstract
We present and analyze a joint source-channel coding strategy for the transmission of a Gaussian source across a Gaussian channel in n channel uses per source symbol. Among all such strategies, our scheme has the following properties: i) the resulting mean-squared error scales optimally with the signal-to-noise ratio, and ii) the scheme is easy to implement and the incurred delay is minimal, in the sense that a single source symbol is encoded at a time.
