What is called an industry-first AI/ML-based neural receiver operating in a live 5G network has been highlighted at MWC 2024.
Vietnam’s Viettel High Technology Industries Corporation (VHT), described as a pioneer of development, manufacturing and commercialisation of telco solutions, and DeepSig, an expert in artificial intelligence (AI) and machine learning (ML) for wireless communications, have announced the industry's first live AI/ML-based neural receiver in a 5G Open virtualised radio access network (vRAN) in Hanoi.
For the first time, says Viettel, AI/ML applied physical layer signal processing is being deployed on 5G ORAN equipment manufactured by VHT in Viettel’s network.
The ongoing collaboration features the integration of DeepSig’s OmniPHY-5G neural receiver software into VHT’s Distributed Unit (DU) based on Intel Xeon processors and Intel FlexRAN reference software to improve 5G user throughput and resource utilisation in an Open vRAN deployment.
The DeepSig software operates channel estimation and equalisation with AI/ML-based algorithms which enhance the signal to interference and noise ratio (SINR) of the physical shared uplink channel (PUSCH).
VHT's DU ORAN equipment system controls many cells with large user capacity and high load in the trial network. The partners say the resulting improvement in 5G RAN capacity and hardware efficiency enables mobile network operators to deliver higher user quality of experience without additional hardware.
Jim Shea, CEO DeepSig, says, “VHT’s urban 5G trial network is an ideal environment for the integrated 5G neural receiver to validate increased radio performance.”
