11. Parameter and State Estimation with Information-rich Signals
Abstract : The complexity of industrial systems and the mathematical models to describe them increases. In many cases, point sensors are no longer sufficient to provide controllers and monitoring instruments with the information necessary for operation. The need for other types of information, such as audio and video, has grown. READ MORE

12. Linearity Enhancements of Receiver Front-end Circuits for Wireless Communication
Abstract : Technology scaling in advanced CMOS nodes has been very successful in reducing the cost and increasing the operating frequency, however, it has also resulted in reduced transistor intrinsic gain and increased thermal noise coefficient, and most importantly, deteriorated linearity performance. At the same time, advanced wireless communication standards offer ever increasing data rates and pose more stringent requirements on coexistence, leading to very stringent linearity requirements.

13. Low-Complexity Signal Processing for Speech Enhancement and Audio Analysis
Abstract : In real-time signal processing there is a constraint to finish processing of an audio signal before the next audio segment is received. This makes it important to have signal processing algorithms with low computational complexity while still maintaining high quality results. READ MORE
