LDPC code construction as a generalized concatenated code
Igor V. Zhilin, Victor Zyablov · 2014
We propose a construction of general concatenated code that uses low-density parity check codes as component codes. This construction itself can also be considered as low-density parity-check code and decoded using Belief Propagation algorithm. Performances of several decoders are compared; it's shown that this code can be efficiently decoded by proposed soft decoding algorithm or combining BP and proposed algorithm.
