    • Various embodiments of the present invention provide systems and methods for min-sum based decoding of non-binary LDPC codes. For example, a non-binary low density parity check data decoding system is discussed that includes a variable node processor and a check node processor. The variable node processor is operable to generate variable node to check node message vectors and to calculate perceived values based on check node to variable node message vectors. The check node processor is operable to generate the check node to variable node message vectors and to calculate checksums based on variable node to check node message vectors. The check node processor includes a minimum and subminimum finder circuit operable to process a plurality of sub-messages in each variable node to check node message vector. The check node processor also includes a select and combine circuit operable to combine an output of the minimum and subminimum finder circuit to generate the check node to variable node message vectors.
