Abstract
A digital communication device is provided for decoding a data stream to generate a receiver output. In the digital communication device, a burst error detector determines burst noise locations corresponding to the data stream according to an error-check equation and accordingly generates a burst error indicator. Thereafter, an inner decoder decodes the data stream to generate an inner decoded stream, comprising an erasure marker for performing an erasure marking process on the inner decoded stream based on the burst error indicator to generate an erasure indicator corresponding to the inner decoded stream. An outer decoder then decodes the inner decoded stream with reference to the erasure indicator to generate the receiver output.
