Abstract

A turbo decoder for decoding a data signal transmitted via a disturbed channel has a symbol estimator and a digital signal processor. The symbol estimator performs two symbol estimations, and the DSP performs an interleaving and deinterleaving procedure, within a computing loop of the iterative turbo decoding. A bidirectional interface is provided for transferring data between the symbol estimator and the DSP.
