Abstract
A system for processing a data signal (such as an ADSL or VDSL signal) includes a first decoder unit, such as a convolutional decoder or a QAM decoder, for receiving the data signal, decoding the second level of encoding and outputting a decoded signal and a first error indication signal indicative of errors in the decoded signal. A redundancy decoder employs the decoded signal and the first error indication signal (or transformed versions thereof) to perform redundancy decoding.
