Experimental demonstration of cycle-slip-tolerant turbo differential decoding for 100-Gb/s DP-DQPSK coherent transmission

We propose and experimentally demonstrate the use of dynamic decoding and limiting to achieve high-performance cycle-slip-tolerant turbo differential decoding in soft-decision LDPC, reducing the differential decoding penalty by 2 dB even in the presence of 10-2 probability of cycle slips.
