Distinguished Lecture (DL) entitled “Phase-Based Time-Frequency Filtering as an Alternative to the Classical Beamforming”
This is to inform you that the Department of CSE (IRD) is organizing a Distinguished Lecture (DL) entitled “Phase-Based Time-Frequency Filtering as an Alternative to the Classical Beamforming” by Dr. Eng. Akihiko K. Sugiyama, Damas.CUS Corporation/Tokyo Metropolitan University, Japan" on 22-08-2025 from 11:30 AM to 12:30 PM in Rose Hall (C-Block, Ground Floor), KLEF Vaddeswaram, – 522302, Guntur District, AP, India.

Phase-Based Time-Frequency Filtering as an Alternative to the Classical Beamforming
This talk presents phase-based time-frequency filtering as an alternative to classical beamforming. The classical beamforming is decomposed into direction-of-arrival estimation and direction-based attenuation. This decomposition makes the design of the 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.
