Cohere Technologies

Cohere Technologies uses a delay-Doppler representation of wireless channels to estimate how radio signals change and predict channel behaviour. Its Universal Spectrum Multiplier software applies those calculations to multi-user MIMO, allowing a cellular sector to spatially multiplex users on shared spectrum. The software is designed for both frequency-division and time-division duplex networks.

Its Multi-G architecture extends this approach into a programmable radio-access physical layer shared across distributed units and a multi-waveform radio unit. Pulsone develops the related Zak-OTFS waveform for satellite connectivity and integrated sensing and communications. These programmes apply channel prediction to communications capacity and radio-based situational awareness, with sensing systems developed through prototypes and research collaborations.
