Signal processing apparatus for setting error indication information according error detection result of outer-code decoder output and related method thereof

摘要

A signal processing apparatus is provided. The signal processing apparatus includes an inner-code decoder, an outer-code decoder, and an error detection unit. The inner-code decoder decodes an input data stream to generate a first output data stream, wherein the input data stream is coded using a concatenated coding scheme including an outer coding and an inner coding. The outer-code decoder decodes the first output data stream to generate a second output data stream. The error detection unit performs an error detection upon the second output data stream to generate an error detection result. The decision logic sets error indication information of the second output data stream according to at least the error detection result.
