Draft:Pulsone

From Wikipedia, the free encyclopedia

Pulsone Technology is a wireless communications technology and business unit developed by Cohere Technologies for Integrated Sensing and Communications (ISAC) networks and Non-Terrestrial Networks (NTN).[1][2] Launched in October 2025, Pulsone is based on the Zak-OTFS (Zak-Orthogonal Time Frequency Space) waveform, which operates in the Delay-Doppler domain rather than the traditional time-frequency domain used by OFDM (Orthogonal Frequency Division Multiplexing).[1][2][3]

The technology is designed to address challenges in high-mobility communications, satellite links, and radar applications.[1][3] Unlike OFDM-based systems that struggle with Doppler shifts and delay spread in Non-Terrestrial Networks, Pulsone Technology leverages the inherent stability of the Delay-Doppler domain for improved performance in dynamic environments.[1][3] The name combines "pulse" (radar sensing) and "tone" (communications), reflecting the technology's dual-use capability for ISAC applications.[3]

Pulsone features improvements for 5G and 6G networks that would enhance defense applications and satellite communications.[1][2][4]

History

[edit]

Cohere Technologies began development of OTFS technology in 2011.[3] The company announced Pulsone as a distinct business unit on October 20, 2025, focusing on ISAC and NTN applications separate from its existing Universal Spectrum Multiplier (USM) product line for 4G/5G networks.[5][1][2]

The first public demonstration occurred at NVIDIA's GTC government conference in Washington, D.C. from October 27–29, 2025, featuring a real-time neural receiver running on NVIDIA's Jetson platform.[1][2][5] This demonstration was conducted in collaboration with researchers from Duke University and Virginia Tech.[1][2] In January 2026, Cohere announced accelerated development efforts for NTN applications and expanded academic partnerships, including the 6G@UT Research Center at the University of Texas at Austin.[6]

Technical architecture

[edit]

Delay-Doppler domain processing

[edit]

Pulsone Technology operates fundamentally differently from OFDM-based systems by processing signals in the Delay-Doppler domain rather than the time-frequency domain.[1][3] The Zak-OTFS waveform uses the Zak transform to convert Delay-Doppler information into time-domain signals for transmission over the wireless channel.[7]

Waveform flexibility

[edit]

Zak-OTFS is designed as a configurable "mother waveform" that can emulate existing 3GPP waveforms, including 5G CP-OFDM, through parameter tuning and pre-coding.[1][2][8]

Neural receiver implementation

[edit]

The Pulsone implementation includes a real-time neural receiver that operates without offline training, addressing a key limitation of conventional neural receivers.[2][4][9][10]
