Abstract
The present invention addresses the deficiencies of prior art joint detection techniques by implementing the decision feedback equalizer part of a joint detector in the turbo decoding iteration loop such that joint detection and turbo decoding are performed interactively in a mutual support fashion. Thus, the decoder (230) benefits from ISI and MAI suppressed samples provided by the equalizer, while the decision feedback equalizer is fed with more reliable hard decisions for the transmitted symbols by the turbo decoder.
