Greetings!

SPS, IEEE Hyderabad Section, in collaboration with The MathWorks India Private Limited, Hyderabad, is organizing a Distinguished Industry Lecture on “Phase-Based Time-Frequency Filtering as an Alternative to the Classical Beamforming” by Dr. Akihiko K. Sugiyama, Dr. Eng., Damascus Corporation / Tokyo Metropolitan University, on 18th August 2025, from 6:30 PM to 8:00 PM at The MathWorks India Private Limited, Hyderabad.

The event will also feature an IEEE SPS Chapter Hyderabad Section Student Branch SPS Faculty Advisors Meet-up.

Abstract
This talk introduces phase-based time-frequency filtering as an alternative to classical beamforming. In this approach, classical beamforming is decomposed into direction-of-arrival estimation and direction-based attenuation. Such decomposition frees the design of the directivity pattern from sensor arrangement constraints, enabling the creation of sharp beams with a small number of sensors.

As an example, audio beamforming for PC applications will be presented, along with a design technique that achieves a constant beam-width across frequencies in multiple channels. Evaluation results demonstrate the effectiveness of this approach, confirming the successful realization of constant beam-width designs.

He has a proven track record of technology adoption in commercial products and international standards, with numerous publications and granted patents. His career uniquely combines research excellence with marketing and sales expertise—developing over 300 new global contacts in just two years and conducting proof-of-concept evaluations with world-leading companies for technical licensing.

He represented Japan in ISO/IEC MPEG Audio standardization, serving as Interim Chair of the Audio Subgroup at the Angra dos Reis Meeting in Brazil, and has also contributed to ITU and 3GPP standardizations. Bridging industry and academia, Dr. Sugiyama has over 25 years of university teaching experience, supervising 75 internship students.

To date, he has delivered 232 invited talks across 101 cities in 31 countries, and received 25 awards, including the prestigious 2024 Industry Innovation Award from the IEEE Signal Processing Society. He is the sole or co-inventor of 273 registered patents in Japan and abroad.

Dr. Sugiyama is a Fellow of IEEE and an Honorary Member and Fellow of IEICE. He has served as a Distinguished Lecturer for the IEEE Signal Processing Society (2014–2015) and IEEE Consumer Electronics Society (2017–2018), as well as a Distinguished Industry Speaker for the IEEE Signal Processing Society (2020–2021). In 2020, the IEEE Consumer Electronics Society recognized him as a Renowned Distinguished Speaker (“The Rock Star”).

Limited seats available. Registration is mandatory and will close at 5:00 PM on 16th August. Don’t miss this opportunity!
Happy to connect with you all.
