Abstract :
We present an approach to eliminate the data-induced interference to the channel estimation of implicit training-aided coherent optical systems by removing the cyclic mean of the transmitted signal. The proposed method shows large improvement in both QPSK and 16-QAM experiments, and can achieve comparable performance as the blind adaptation scheme.
