Cohere Technologies and Academic Researchers will Jointly Demonstrate the Neural Receiver at the NVIDIA GTC Conference, taking place in Washington D.C., October 27-29
SAN JOSE, CA, OCTOBER 20, 2025 — Cohere Technologies, the innovator of Universal Spectrum Multiplier (USM) software for 4G and 5G networks, and Zak-OTFS powered by Pulsone™ Technology designed for ISAC and NTN, today announced that it will join researchers from Duke University and Virginia Tech (Virginia Polytechnic Institute and State University) to show a joint collaboration demonstration of the industry’s first real-time Neural Receiver that works in complex Delay-Doppler channel environments, enabling situational and operational awareness to track many high-speed objects — as required by future Integrated Sensing and Communications (ISAC) networks.
At NVIDIA’s GTC government conference, the three parties are demonstrating an ISAC solution with the Zak-OTFS waveform and a real-time Neural Receiver using NVIDIA’s JetsonTM Platform. Pulsone Technology by Cohere leverages the Zak-OTFS waveform to deliver improved stability even in complex Delay-Doppler environments — enabling wireless channel situational awareness using data-derived sensing. The neural receiver is unique in that it requires no offline training and operates at the speed of wireless. The demo shows live video and a simultaneous radar view of the wireless channel. The Zak-OTFS waveform carries information in the radar domain and is ideally suited for ISAC. The Neural Receiver can train in real time to receive any waveform and converges within the timeframe of a single symbol, addressing critical warfighter challenges around multiprotocol requirements and power consumption.
“This demonstration marks a pivotal moment for ISAC networks, showing that low-complexity and robust real-time Neural Receivers can deliver fully integrated sensing and communications without compromise,” said Dr. Anton Monk, SVP Technology Strategy at Cohere Technologies. “With Cohere’s Zak-OTFS Pulsone™ Technology, we’re unlocking situational awareness capabilities through next-generation ISAC networks that will shape the future of defense and US national security interests.”
“The real-time Zak-OTFS 2D Neural Receiver brings to reality the vision of a unique, low-complexity universal receiver that operates without offline training”, said Dr. Lingjia Liu, the Andrew J. Young Professor of Electrical and Computer Engineering at Virginia Tech. “This milestone of online learning-based neural receiver opens the door to flexible, resilient, and real-time ISAC networks that can operate seamlessly across waveforms, protocols, and missions, redefining what is possible for next-generation wireless networks.”
“Stability of Zak-OTFS in the Delay-Doppler domain enables full integration of sensing and communication with no loss in spectral efficiency,” said Dr. Robert Calderbank, Director of the Information Initiative and Professor of Electrical Engineering, Computer Science and Mathematics at Duke University. “Using Zak-OTFS enables networks to deliver real-time situational awareness as a built-in capability.”
