Abstract
A turbo-code decoder with iterative channel parameter estimation for decoding turbo-coded received data that includes systematic information data and redundant data. The turbo-code decoder includes a weighting circuit for weighting the turbo-coded received data with at least one estimated channel parameter. Estimated value data is generated. A turbo-code coding circuit turbo-codes the generated estimated value data. A comparison circuit compares the turbo-coded estimated value data with the turbo-coded received data, and depending on the result of the comparison, iteratively sets the estimated channel parameter(s) in order to weight the turbo-coded received data.
