Abstract

A stepped low density parity check (LDPC) codes punching algorithm based on multiple check matrices is proposed. The proposed scheme is more flexible to realize the adaptive rate under Gaussian white channel. In a 100Gbit/s optical communication simulation system, the proposed algorithm has about 0.49dB gain after 1000km of transmission, compared to the general punching algorithm.
