Abstract
Systems and methods for acquiring a first set of information for a plurality of low density parity check (LDPC)-encoded data symbols, acquiring a second set of information for the plurality of LDPC-encoded data symbols, and selecting a window including a subset of the plurality of LDPC-encoded data symbols. The systems and methods include acquiring a decoder schedule having information for controlling the decoder, wherein the information in the decoder schedule includes decoding instructions based on a configuration of at least one of the first set of information and the second set of information. The systems and methods further include determining a likelihood of an error in the window using the decoding instructions in the decoder schedule, and updating the second set of information for selected data symbols of the subset based on the likelihood of an error in the window.
