Board Promotes Cohere’s OTFS™ Waveform as Key to Meeting 5G Requirements
SANTA CLARA, Calif., – February 08, 2017 – Cohere Technologies (cohere-technologies.com) has formed a technical advisory board to assist the company in bringing its groundbreaking OTFS™ wireless waveform technology to market. The board members are major figures in academia and business who are responsible for many of the technology breakthroughs that enable today’s high-speed wireless and mobile services.
“We formed our technical advisory board in response to the considerable industry interest in our OTFS technology, which has grown substantially over the past two years as we conducted successful technical trials and simulations with our operator partners,” said Dr. Ronny Hadani, chief technology officer at Cohere Technologies. “In addition to encouraging further technical investigation of OTFS, the board will also help us identify new applications beyond our current market focus. Complementing their technical expertise, the advisory board members also have proven track records on the business side of wireless that Cohere will leverage to develop new technology partner relationships and expand our approach to new markets.”
The board’s efforts will complement the public support Cohere has already received from several of the world’s top wireless carriers calling for an investigation into OTFS and its potential to play a role in 5G.
“Cohere’s OTFS is the first major breakthrough in waveform design in many decades, and is uniquely poised to meet the requirements of 5G,” said technical advisory board chair Dr. Andrea Goldsmith of Stanford University. “Every new generation of cellular system has promised a range of compelling new applications, and adopted a new waveform to meet the associated requirements.”
Dr. Robert Calderbank of Duke University added: “It is difficult to predict which applications will dominate, and which disruptive technologies will succeed, but growth in demand for wireless services will surely increase the cost and complexity of configuring and operating wireless systems. OTFS is a breakthrough in waveform design, with deep mathematical roots in the theory and practice of radar, that offers a path to future-proofing 5G.”
“Support for mobility has been a key feature of cellular systems since their inception. Yet the waveform designs for cellular are based on traditional wireless principles where the channel is treated as being static,” said Dr. Robert Heath of the University of Texas at Austin. “Cohere Technologies is pioneering a new waveform with ground-up support for high doppler and wideband channels. Cohere’s OTFS waveform scheme is a major departure from the way the industry has approached wireless, and shows promise for the major 5G use cases. It is an honor and privilege to sit on a technical advisory board with many intellectual leaders in wireless communication.”
Board member Dr. Arogyaswami Paulraj, a principal figure responsible for the MIMO (Multiple Input Multiple Output) concept that is key in today’s 4G cellular and Wi-Fi networks, added “the Emerging 5G standard promises dramatic performance gains over 4G in terms of capacity, coverage and reliability, but for 5G to achieve this it will be necessary to overcome increasing new challenges, such as the problems of pilot overhead which will be significantly worse. Fortunately, Cohere’s OTFS shows significant promise to mitigate these pilot challenges.”
The technical advisory board will be led by Dr. Hadani and Dr. Anton Monk, Cohere’s vice president of strategic alliances and standards. The initial board members are:
Professor Andrea Goldsmith
Andrea Goldsmith is the Stephen Harris professor in the School of Engineering and a professor of Electrical Engineering at Stanford University. She also founded and served as CTO of Quantenna Communications, which developed the first 4×4 802.11n chipsets. Dr. Goldsmith is a Fellow of the IEEE and of Stanford, and has received several awards, including the IEEE ComSoc Edwin H. Armstrong Achievement Award, the National Academy of Engineering Gilbreth Lecture Award and the Silicon Valley/San Jose Business Journal’s Women of Influence Award. She authored “Wireless Communications” and co-authored “MIMO Wireless Communications” and “Principles of Cognitive Radio,” both published by Cambridge University Press. She is also an inventor on 29 patents.
Professor Robert Calderbank
Dr. Robert Calderbank is director of the Information Initiative at Duke University, where he is Professor of Electrical Engineering, Computer Science and Mathematics. Before joining Duke he was Professor of Electrical Engineering and Mathematics at Princeton University where he also directed the Program in Applied and Computational Mathematics. Before joining Princeton University Dr. Calderbank was vice president for research at AT&T where he managed AT&T intellectual property, and was responsible for licensing revenue.
Professor Robert Heath
Dr. Robert W. Heath Jr. is a professor in the department of Electrical and Computer Engineering at the University of Texas at Austin, and holds the Cullen Trust for Higher Education Professorship in Engineering. He played a central role in designing and implementation of the physical and link layers of the first commercial MIMO-OFDM communication system while at Iospan Wireless from 1998 to 2001. Professor Heath’s research interests include several aspects of wireless communication and signal processing: limited feedback techniques, multihop networking, multiuser and multicell MIMO, interference alignment, adaptive video transmission, manifold signal processing, and millimeter wave communication techniques.
Professor Emeritus Arogyaswami Paulraj
Dr. Arogyaswami Paulraj is Professor Emeritus (research) of engineering and a Marconi Society Fellow in the department of Electrical Engineering at Stanford University. He proposed the MIMO (Multiple Input Multiple Output) concept which is the key to 4G cellular and Wi-Fi wireless networks in 1992. He is a co-inventor of 66 U.S. patents and the author of over 350 research papers and two text books. He is an ISI Thompson Highly Cited Researcher. Professor Paulraj has won over a dozen awards in the US, notably the 2011 IEEE Alexander Graham Bell Medal and the 2014 Marconi Prize and Fellowship, both top awards for telecommunications technology pioneers. He is a fellow of eight national engineering/science academies including those in the US, China, India and Sweden. He is a fellow of IEEE and AAAS. In 1999, Paulraj founded and served as CTO of Iospan Wireless, which developed and established MIMO-OFDMA wireless as the core 4G technology.
About Cohere Technologies
Cohere Technologies is solving the most pressing challenges in wireless communications with its groundbreaking Orthogonal Time Frequency and Space (OTFS) technology. This new 3D modulation scheme will revolutionize the industry as it prepares to deliver the promise of 5G with 100 percent coverage, 10x spectral efficiency and a 50 percent cost savings over existing solutions by perfectly capturing the wireless channel. OTFS can also enhance traditional modulation schemes with its greater capacity and coverage to make 5G mobility a reality. Top carriers are testing OTFS and the company is developing OTFS-based solutions for backhaul, fixed wireless access and 5G applications.
