RF pilot tone phase noise cancellation based on DD-MZM SSB modulation for optical heterodyne RoF link

A Simplified Deep-Learning-based Phase Noise Tolerant Radio-Over-Fiber Receiver

“…In addition, a new receiver architecture incorporating deep learning (DL) at the receiver of an RoF link was proposed and demonstrated on an unlocked heterodyning RoF link [2] with results suggesting that the receiver has a greater tolerance against phase-induced noise and may perform better than conventional self-homodyning (SH) based receiver in certain scenarios. However, the DL-based receiver architecture has a higher complexity compared to heterodyned-based receivers [3] and conventional SH-based receiver, making it a less compelling alternative relative to aforementioned alternatives. Hence, we propose a simplified version of the DL-based phase noise tolerant RoF receiver, as shown in Fig.…”
