Joint Demapping and Decoding for DQPSK Optical Coherent Receivers
Mario A. CastrillonDamian A. MoreroMario R. Hueda
文献摘要
We present a low-complexity joint demapper-decoder scheme for coherent optical receivers with DQPSK modulation. The new technique reduces to 0.7dB the gap between QPSK and DQPSK in 100Gb/s coherent optical systems.
