A novel method is proposed to compensate polarization crosstalk induced by interchannel nonlinearity. Experiments have demonstrated that the proposed method provides over 1 dB performance improvement for 112 Gb/s dual-polarization QPSK coherent receivers.
The Viterbi-and-Viterbi (V-V) algorithm is widely used to recover the carrier phase in optical digital coherent receivers. For simplicity, the basic V-V algorithm assumes constant carrier phase within the average duration. However, this basic assumption is probably violated by factors such as laser frequency offset and nonlinear XPM. In order to improve the basic V-V carrier phase recovery, five methods...
Enhanced digital signal processing algorithms are proposed and evaluated experimentally in order to improve the tolerances to intra-channel and inter-channel nonlinear effects of intradyne receiver and thus to extend the reach of WDM transmission systems.
A novel frequency offset estimator is proposed and implemented in a 1 Gbit/s real-time coherent receiver to demonstrate all-digital frequency offset compensation up to plusmn0.4 symbol rate.
