Ronny Hadani (Hebrew: רוני הדני) is an Israeli-American mathematician, specializing in representation theory and harmonic analysis, with applications to signal processing.

[1][2] He is known for developing Orthogonal Time Frequency and Space (OTFS) modulating techniques, a method used for making wireless 5G communications faster,[3] that is also being considered for use in 6G technology.

The company is a Silicon Valley wireless startup that focuses on wireless improvements using OTFS and the Delay-Doppler model to improve FDD/TDD spectrum performance with channel detection, estimation, prediction, and precoding software for 4G and 5G networks, compliant with 3GPP standards and O-RAN.

[5][10][12] In December 2022, during the inaugural 6G Evolution Summit event opening keynote, Fierce Wireless moderator referred to Hadani as “The Father of OTFS.”[13] Hadani has been granted over 70 OTFS related patents, which include a communications method employing Orthogonal Time Frequency Space (OTFS) shifting and spectral shaping, which allows users to transmit and receive at least one frame of data ([D]) over a wireless communications link.

[7][14][15] His OTFS technology has been tested by companies such as C Spire, 5TONIC,[15][16] Telefónica,[17] and Deutsche Telekom,[18][19] According to Google Scholar, Hadani has published over 75 research papers and patents.
