A density evolution procedure for low-density parity-check (LDPC) codes under layered decoding was presented. The convergence threshold and characteristic of layered decoding were analyzed and compared with common belief propagation and min-sum algorithm. It is found that the layered decoding does not improve noise threshold but it can reduce the decoding iteration by half.
