Abstract

Abstract : Non‐binary turbo codes promise excellent performance for a wide range of applications and environments, but research in this area is sparse. The performance of a non‐binary turbo code defined in GF(4) on a two‐way wireless relay channel (TWRC) employing physical‐layer network coding, which is affected by impulsive noise is investigated. Simulation results for binary and non‐binary turbo codes are presented and validated with an error floor analysis at the relay of the TWRC and it is observed that non‐binary turbo codes significantly outperform binary turbo codes at low signal‐to‐noise ratios.
