Cross-reference-based sampling frequency offset estimation method for 60-Gbps 50-m photonics-aided D-band IM/DD wireless transmission system
In this article, we successfully realize 60-Gbps 50-m photonics-aided D-band IM/DD wireless transmission, enabling by a novel cross-reference-based (CRb) sampling frequency offset (SFO) estimation method. We analyze it through theoretical derivation, simulation, and experimentation, enabling the BER of a 30-GBaud PAM-4 signal calculated from up to 2,998,272 continuous symbols within a 100-us time window meeting the 25% SD-FEC threshold. Besides, all the outcomes prove the effectiveness of the proposed method, which can enhance the performance of future optical wireless communication systems and other digital DSP-based communication systems.
