How ldpc works
Web12 sep. 2024 · LDPC codes are a class of linear error-correction codes on sparse bipartite graphs providing efficient decoding using message passing (between variable and check nodes on the graph) and excellent error correction performance. WebThe next step is to convert the 91-bit message to the so-called LDPC (Low-density parity-check) code with a 174 bits length — this redundancy is used to correct errors during the …

Web13 jun. 2024 · As commonly implemented, if you ‘pad’ 100 bytes, this means the first 100 bytes of the 255 code block are assumed to be zero, and are not transmitted. This turns a (255,223) code into (155,123). Using padding can save a lot of bandwidth, while not “wasting” parity.
