Keysight Technologies, Inc. (NYSE: KEYS) has collaborated with
NVIDIA to create a complete design flow for training and validating
neural receivers that will be shown at Mobile World Congress
Barcelona 2024. To be presented at Keysight’s booth, Hall 5 Stand
5E12, the demonstration will feature an Open RAN testbed that has
been augmented by a multi-user MIMO neural receiver.
While 5G integrates artificial intelligence (AI) to enhance
specific components in wireless networks, 6G will be the first
generation of wireless technology that is AI-native. A key goal is
to develop site-specific neural receivers to replace the entire
human-designed receive chain of the physical layer. Yet, the data
required to train these neural receivers is limited, and validating
their performance in end-to-end systems presents a challenge.
Before neural receivers can be deployed in commercial networks,
they need to be adequately trained, demonstrated to surpass
traditional receivers in performance and shown to robustly handle
the channel conditions of real-world networks.
This demonstration shows how Keysight solutions enable the
design and validation of a neural receiver. With the NVIDIA Sionna
library used to train the neural receiver, ray-traced channels
allow for site-specific training data generation and hence the
creation of digital twins of real-world systems. As such, the
neural receiver can be optimized for any intended environment.
When the training is complete, the neural receiver is deployed
in an Open RAN testbed using Keysight’s equipment connected to a
FlexFi commercial radio unit from LITEON Technology. To emulate the
site-specific channel, the Keysight PROPSIM channel emulator is
used. It allows for the seamless import of ray-traced channel
impulse responses. The trained neural receiver then demodulates the
signal. Measurements of the block error rate of the end-to-end
system provide insights into the neural receiver’s performance.
Giampaolo Tardioli, Vice President, 6G and Next Generation
Technology at Keysight, said: “By collaborating with industry
leaders like NVIDIA, Keysight is helping provide the tools and
insights needed to allow artificial intelligence to move into the
mainstream for wireless communications. Through use of our
simulated and measured data for training digital twins of Open RAN
networks and the validation of AI performance, we are able to
provide the complete end-to-end design environment that is needed
to develop neural receivers and other AI components for 6G.”
Ronnie Vasishta, Senior Vice President of Telecom at NVIDIA,
said: “Software-defined RAN enables the native integration of
AI across the entire protocol stack, ultimately leading to 6G
systems that can optimally adapt to any environment. Keysight’s
ability to generate and capture real-world data for training and
evaluation, bolstered by the open-source NVIDIA Sionna library for
6G physical-layer research, is a key element helping to drive the
adoption of AI in wireless networks.”
This demonstration includes technology that was developed as
part of CENTRIC and 6G-SANDBOX, projects that have received funding
from the Smart Networks and Services Joint Undertaking (SNS JU)
under the European Union’s Horizon Europe research and innovation
program under Grant Agreement No 101096379 & 101096328,
respectively.
