Abstract
In this paper, we propose a new turbo equaliser which outputs marginal a-posteriori probabilities of each symbol. These marginal a-posteriori probabilities can be used directly by the decoder in the turbo process. We show how this equaliser is particularly interesting in the context of turbo decoding and also allows to perform blind channel estimation. We will finally show that this new method brings out significant improvements over the classixal Interference Canceller (lower SNR threshold or trigger point) with an acceptable computational cost.
