ABSTRACT:
Systems and methods for iterative decoding in the presence of burst errors are provided. The methods include acquiring extrinsic and channel information for received ECC-encoded data symbols, selecting a window including a subset of the received ECC-encoded symbols, determining the likelihood of a burst error in the window, and updating channel information for selected data symbols in the window. In one embodiment, burst error detection circuitry is used to determine the likelihood of a burst error in the window.
