In this invited paper, we describe a rate-adaptive FEC scheme based on LDPC codes together with its software reconfigurable unified FPGA architecture. By FPGA emulation, we demonstrate that this class of rate-adaptive LDPC codes based on shortening with an overhead from 25% to 42.9% provides a coding gain ranging from 13.08 dB to 14.28 dB at a post-FEC BER of 10−15 for BPSK transmission. In addition, the proposed rate-adaptive LDPC coding combined with higher-order modulations have been… CONTINUE READING
