Abstract :
Training-aided frequency-domain equalization for coherent receivers based on digital-signal-processing with oversampling factor below 2 samples-per-symbol (sps) is reported. The proposed architecture shows no performance degradation by reducing the oversampling factor from 2 to 1.25 sps.
