Abstract:
Techniques are described for performing a bit-flipping decoding scheme on a G-LDPC codeword. In an example, a decoding system uses two syndrome tables. The first syndrome table identifies a predefined syndrome for a component codeword that protects a bit of the G-LDPC codeword. This predefined syndrome is identified based on a location of the bit and is used to update a current syndrome of the component codeword. The second syndrome table identifies one or more bit error locations for the component codeword. The bit error locations are identified from the second syndrome table based on the current syndrome of the component codeword, as updated. In an example, the error locations are used to update a reliability of the bit if its location corresponds to one of the error locations. A bit flipping decision is made for the bit based on its reliability.

Claim (Index 15):
The G-LDPC decoding system of  claim 14 , wherein the first syndrome table is defined based on:\n initializing a simulation component codeword to \u201c0;\u201d and iteratively performing operations comprising:\n setting a single bit of the simulation component codeword to \u201c1,\u201d wherein the single bit is at a location in the simulation component codeword; \n computing a syndrome of the simulation component codeword with the single bit set to \u201c1;\u201d and \n adding the syndrome to an entry of the first syndrome table, wherein the entry is associated with the location of the single bit in the simulation component codeword.
