Abstract
A new iterative equalisation-decoding scheme is presented in which the deco der provides not only extrinsic information but also hard decisions of the coded bits for the next iteration. In the equaliser, the extrinsic informat ion is used as the a priori probabilities of the transmitted bits, while ha rd decisions of the coded bits are utilised to improve the channel estimati on. As a result, a significant gain in performance is achieved with respect to conventional iterative schemes in practical mobile channels.
