  • Abstract
    A novel three-stage digital feed-forward carrier recovery algorithm based on the transformation of 64-QAM constellation into QPSK is proposed. For 1 dB penalty at BER=10-2, it can tolerate a linewidth-times-symbol-rate product of 4.5·10-5, making it possible to operate 32-Gbaud optical 64-QAM systems with current commercial tunable lasers.
