At the upcoming #MWC24 in Barcelona, Keysight Technologies and InterDigital plan to demonstrate how AI channel estimators can be trained, integrated into a physical layer, and evaluated.
The companies expect that AI will be a foundational technology for 6G, where it will be used for channel estimation. When the channel estimation block is replaced with a neural network (NN), site-specific training data used for the NN can optimize its performance and robustness to new use cases.
The demonstration uses Keysight’s communications system-specific Electronic Design Automation (EDA) software to model a 3GPP physical layer and wireless channels. Instead of using the traditional channel estimation signal processing, this block has been replaced with various neural networks for channel estimation. The first NN was fully developed and trained by InterDigital and delivered to Keysight. The second NN was developed by Keysight and trained in two different ways. First using a combination of data generated by Keysight’s Electronic Design Automation System (SystemVue) software and then again using real-world measurement data. The demonstration compares performance and complexity of InterDigital and Keysight’s Machine Learning approaches to that of traditional channel estimation, and uses an EDA software environment and a real-world 144 GHz over-the-air environment.
Milind Kulkarni, Vice President and Head of Wireless Labs at InterDigital, said: “Through partnership with Keysight, we are able to extend our ability to validate AI solutions for wireless networks. These types of collaborations and their outcomes provide valuable insight and build industry alignment as we work to shape how AI will be used in both 5G and 6G.”
Giampaolo Tardioli, Vice President, 6G and Next Generation Technology at Keysight, said: “The world is embarking on a transformative journey to revolutionize the future of connectivity with the use of AI in wireless communications. Our collaboration with strategic partners like InterDigital enables us to hone our solutions and capabilities to meet the needs of our customers as they continue pushing the boundaries of what is possible when AI and wireless are combined.”
