Abstract

We experimentally investigate the bit error rate(BER) performance of soft-decision low density parity check (LDPC) turbo decoding (Turbo-LDPC) in a 56Gbit/s high power sensitivity DQPSK coherent communication system. Power sensitivity of -38.3dBm and -39.3dBm are realized by using LDPC and Turbo-LDPC, respectively. Turbo-LDPC outperforms LDPC by 1dB. Turbo-LDPC successfully decodes signals with 1.8E-2 pre-(forward error correction) FEC BER and traditional LDPC decoder fails to decode error free above 2.6E-2 pre-FEC BER.
