Abstract

Feed forward neural network are very powerful devices for soft-decision decoding of linear block codes. A practical realization for a (7,4) BCH code is presented. The relationship between maximum likelihood decoding, winner-takes-all neural networks and neural networks with a sigmoidal response function is established. It is shown how learning with an error back propagation algorithm can drastically improved the performance of the decoding network in the case of an additive gaussian channel with memory.
