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...
Training Sequence Length Optimization for a Turbo-Detector Using Decision-Directed Channel Estimation
Training Sequence Length Optimization Turbo-Detector Decision-Directed Channel Estimation
2009/9/4
We consider the problem of optimization of the training sequence length when a turbo-detector composed of a maximum a posteriori (MAP) equalizer and a MAP decoder is used. At each iteration of the rec...
Improved Nonlinear Tolerance of 112-Gb/s PDM-OFDM in Dispersion-Uncompensated Transmission with Efficient Channel Estimation
Nonlinear Tolerance PDM-OFDM Dispersion-Uncompensated Transmission Efficient Channel Estimation
2015/7/30
We show numerically that the nonlinear tolerance of a 112-Gb/s PDM-OFDM signal, coherently received with a robust and efficient channel estimation method, is substantially improved by fiber dispersion...
