Ldpc thesis

Chapter 9 ldpc codes low density parity check (ldpc) codes make up a class of block codes that are characterized by a sparse parity check matrix. Low-density parity-check (ldpc) codes are a class of linear block ldpc codes the name comes from the characteristic of their parity-check matrix which contains only a few 1’s in comparison to the amount of 0’s their main advantage is that they provide a performance which is very close to the capacity for a lot of different channels and.
