Blind decoding in $\alpha$-Stable noise: An online learning approach

Abstract

A novel method for performing error control coding in Symmetric $\alpha-$Stable noise environments without any prior knowledge about the value of $\alpha$ is introduced. We use an online learning framework which employs multiple distributions to decode the received block and then combines these results based on the past performance of each individual distributions. The proposed method is also able to handle a mixture of Symmetric $\alpha-$Stable distributed noises. Performance results in turbo coded system highlight the utility of the work.
