Channel Estimation with Weighed Intra-symbol Averaging in Coherent Optical Transmission Systems

摘要：

　　A frequency-domain channel estimation with weighed intra-symbol averaging (WISA) technique has been presented in this paper.The tolerance towards nonlinearity has been investigated in a 224Gbit/s 16QAM coherent optical system by simulation.System performance is evaluated with the Q factor when increasing the transmission distance from 800km to 1440km.Simulation results demonstrate that the WISA based channel estimation surpasses intra-symbol averaging based channel estimation by 13.3%in terms of maximum transmission distance when Q factor threshold is 8.5dB.
