Design and Implementation of a High-precision Wireless Clock Synchronization System Based on UWB
2022 4th International Conference on Intelligent Control, Measurement and Signal Processing (ICMSP)（2022）
School of Automation
Abstract
The performance of wireless distributed systems is largely determined by the accuracy of clock synchronization. However, most of the current high-precision clock synchronization solutions rely on GNSS or other auxiliary sources to complete. In this paper, a multi-agent cooperative wireless high-precision clock synchronization solution based on Ultra-Wide Band (UWB) is proposed. Through the measurement and calculation of the distance and delay between nodes, and the multi-agent consistency theory, high-precision wireless network clock synchronization is realized. The designed solution is verified based on the hardware-in-the-loop verification system. Experimental results show that the method can achieve clock synchronization better than 1ns.

- 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
