A turbo decoder for decoding a data signal transmitted via a disturbed channel has a symbol estimator. The symbol estimator contains a computing device, which, with knowledge of the error protection code used at the transmitter end, calculates transition metric values, forward and reverse recursion metric values and the output values (LLR). The computing device includes at least one hardware computing chip constructed of combinatorial logic for generating at least one type of the values.
