Topic:

Phase-Based Time-Frequency Filtering as an Alternative to the Classical Beamforming

This talk presents phase-based time-frequency filtering as an alternative to the classical beamforming. The classical beamforming is decomposed into direction-of-arrival estimation and direction-based attenuation. This decomposition makes the design of directivity pattern free from the sensor arrangement, enabling a sharp beam with a small number of sensors. Audio beamforming for PC applications is presented as an example with a design technique for a constant beam-width across the frequency in multiple channels. Successful evaluation results confirm the constant beam-width design.

Biography:

40+ years of experience developing telecommunications, speech, and audio signal processing systems for consumer and network system products. In addition to proven record of technology adoption in products and international standards as well as publication and granted patents, marketing and sales experience to develop over 300 new contacts in the world in two years and proof-of-concept (PoC) evaluations with world-leading companies for technical licensing are unique as a research engineer.

Once representing Japan for ISO/IEC MPEG Audio standardization including an Interim Chair of the Audio Subgroup at the Angra dos Reis Meeting in Brazil, experiences extend to ITU and 3GPP standardizations as a delegate. Established a bridging career between industry and academia through 25+-year teaching experience at universities and supervision of 75 internship students. Delivered 239 invited talks in 107 cities in 31 countries, and received 25 awards including the 2024 Industry Innovation Award by IEEE Signal Processing Society. The sole inventor or a co-inventor of 273 registered patents in Japan and overseas. Fellow of IEEE as well as Honorary Member and Fellow of IEICE. A Distinguished Lecturer for Signal Processing Society (2014-2015) and Consumer Electronics Society (2017-2018), and a Distinguished Industry Speaker for Signal Processing Society (2020-2021), IEEE.
