Advanced Machine Learning-Powered Tunable Optical Signal Processor for Precise Chromatic Dispersion Compensation in Analog B5G/6G Mobile Fronthaul Networks
MACHINE LEARNING IN PHOTONICS（2024）
Abstract
We introduce an ML-driven optical signal processor for dispersion compensation in B5G RAN. This approach leverages a reconfigurable, energy-efficient MRR structure, effectively mitigating power fading. Our study exploits M-QAM digitally up-converted A-IFoF transmission simulation results to fiber distances up to 25km to prove the capabilities of the designed machine learning-based analog photonic processing unit. Analytical MATLAB calculations show enhanced output power, corroborated by VPI simulations demonstrating improved EVM values, including 16.9% EVM for 1GBd QPSK at 8.5GHz over 25km, meeting the 3GPP standards.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
