Talk A

Title: Active noise control theory and applications

Active noise control (ANC), as one of the cutting-edge technologies, has been paid a lot of attention in recent years. In this talk, after introducing some fundamentals of ANC theory, several recent achievements recognized in the ANC community regarding the ANC system structures and adaptive algorithms are explained in some detail. Focus of my talk is put on the introduction of advanced narrowband ANC systems and sophisticated algorithms that have been proposed and refined by my research group. Interesting real-world applications of ANC is also provided. Finally, some open topics of ANC are discussed.

Talk B

Title: Linear and nonlinear adaptive noise cancellers and applications

Active noise cancellation has many applications in control, biomedical engineering, digital communications, speech signal processing and so forth. In this talk, I will focus on applications to fetal ECG extraction and noise reduction of speech signals. The former has been an important application of adaptive signal processing from the 1970s, but no extraction system has been put into use in medical diagnosis. Some new results obtained in my lab will be presented and explained in some detail. The latter is a relatively new application that enjoys huge potentials for many perspective implementations. It is based on the use of severely polluted air-conducted speech measurements and relatively clean bone-conducted signals.
