Abstract

This paper investigates radial basis function-based turbo equalization (TEQ) applied to non linear communication channels via satellite. This channel is considered as a Volterra model. The paper deduces the soft input soft output (SISO) radial basis function (RBF) equalizer that can be implemented in an iterative algorithm to improve the system performance. Reduced complexity implementations are also presented, especially feedback (FB) method is considered in this paper. The aim of this paper is to analyse equalizer parameters, namely delay and feedback, they are analysed in order to point to the optimal design of the TEQ. The paper shows the ability to choose optimal equalizer parameters using the EXIT chart technique. Achievable rate curves, from source to destination, are given within different values of the equalizer parameters.
