ITERATIVE DECODING USING RE-ENCODING BETWEEN DECODING STAGES

Aspects of the present disclosure are directed to decoding signals susceptible to communication errors. As may be implemented in accordance with one or more embodiments, an input signal is decoded (110) to produce a first decoded output, which is subsequently encoded (120), and error characteristics of the encoded first decoded output are assessed (130). The input signal is again decoded (140) (e.g., with a delay), using the encoded first decoded output and the assessed error characteristics thereof to assess a reliability characteristic of bits in the input signal. A second decoded output is then provided with errors corrected therein based on the assessed reliability characteristic.
