Channel Estimation Using Superimposed Training for Coherent Optical OFDM Systems
Channel Estimation Superimposed Training Optical OFDM Systems
2016/12/2
We demonstrate by simulation that the superimposed training based channel estimation scheme can achieve similar performance as compared with conventional schemes, without any loss in bandwidth. An ite...
PDL Mitigation in PolMux OFDM Systems using Golden and Silver Polarization-Time Codes
Fiber optics communications Optical communications Modulation
2015/6/4
Polarization-Time coding can highly mitigate PDL impairments in optical OFDM sys-tems. The performances of two full-rate Polarization-Time codes, the Golden and Silver codes, have been evaluated showi...
