In this letter, we analyze the convergence speed of layered decoding of block-type low-density parity-check codes and verify that the layered decoding gives faster convergence speed than the sequential decoding with randomly selected check node Subsets. Also, it is shown that using more subsets than the maximum variable node degree does not improve the convergence speed.
