Methods and systems for reconfigurable LDPC decoders

摘要

The present disclosure includes 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 present disclosure includes 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 present disclosure further includes 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.

1. A method for decoding data, the method comprising:
acquiring, at a decoder device, first information and second information for a low density parity check (LDPC)-encoded data symbol; acquiring a decoder schedule, wherein the decoder schedule includes decoding instructions based on a configuration of at least one of the first information and the second information; determining an error parameter for the LDPC-encoded data symbol based on the decoding instructions; and updating the second information based on the error parameter.
