    Bringing ISAC and Multiple Waveforms to the OCUDU RAN Stack

    In July 2026, Cohere was awarded a DoW contract to build a mission-first ISAC sensing platform via integrating the Zak-OTFS wireless system, Multi-RAT Spectrum Sharing, and a novel Neural Receiver into the Linux Foundation’s OCUDU RAN stack.

    The Economic Benefits of New, Radar-based Communications Platform

    The Universal Spectrum Multiplier and it’s ECHO dataset significantly increase the value of 5G assets by delivering 6G-grade capabilities, such as mission-first Integrated Sensing (ISAC) and AI-native optimization, on existing infrastructure now.

    Significantly Improving Performance of Zak-OTFS based ISAC

    The researchers designed a Zak-OTFS based radar waveform that significantly improves target resolution in both delay and Doppler domains which minimize image blurriness and feature reduced signal processing complexity. Additionally, this discrete approach demonstrates a 100 dB reduction in sidelobes compared to traditional Zadoff-Chu sequences that are proposed for 5G.

    Multi-G – The Mathematical Unification of 5G and 6G Candidate Modulations

    Mathematically, 5G’s OFDM and 6G contenders like Zak-OTFS are actually specific versions of a single family called complex Hadamard-modulated pulse trains. This theoretical unification allows for a true Multi-G transceiver architecture capable of supporting multiple waveforms simultaneously. By multiplexing these different schemes, operators can better serve diverse user needs within a single 6G network.

    The Implications of Holographic Channel Insights

    This deep dive covers our collaboration with Bell, from the early integration of the Universal Spectrum Multiplier (USM) into a live OEM 5G base station to the groundbreaking Enhanced Channel Insight with Holographic Observability (ECHO) add-on. ECHO empowers millions of deployed 5G base stations globally to participate in AI-RAN without a forklift upgrade.

    Multi-G Innovation for ISAC: Making the case for Orthogonal Time Frequency Space

    International standards, 6G practicalities, Integrated Sensing, and OTFS come together in this conversation.

    How will “Learning in the Delay-Doppler Domain” transform our handling of the wireless channel?

    This deep-dive exposes a transformational approach proposed by Dr. Rob Calderbank of Duke University to using OTFS’ Delay-Doppler capabilities to operate “model free” while sending traffic over wireless channels. This adaptive and self-optimizing notion has positive implications to future use of higher frequency and doubly spread channels proposed for 6G spectrum.

    What is Integrated Sensing and Communications (ISAC) and how does OTFS implement it?

    In this podcast OTFS is examined for its capabilities to implement both data transmission and sensing in same transmissions. Additionally, applications use cases for ISAC and simulation results will be discussed.
