36. Low-Complexity Signal Processing for Speech Enhancement and Audio Analysis
Sammanfattning : 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. LÄS MER
37. Implementation and Evaluation of Signal Processing Circuits for Optical Communication
Sammanfattning : The digital signal processing (DSP) circuits used in the fiber-optic communication links that make up the backbone of the Internet can be a significant contributor the over-all power dissipation of a link. As the number of connected users and their bandwidth requirements are expected to continue to grow over the coming years, the development of power-efficient high-throughput DSP systems is a critical factor in enabling this growth.

39. Expressing emotions through vibration for perception and control
Sammanfattning : This thesis addresses a challenging problem: “how to let the visually impaired ‘see’ others emotions”. We, human beings, are heavily dependent on facial expressions to express ourselves. A smile shows that the person you are talking to is pleased, amused, relieved etc. LÄS MER
40. Nonlinear phonocardiographic Signal Processing
Sammanfattning : The aim of this thesis work has been to develop signal analysis methods for a computerized cardiac auscultation system, the intelligent stethoscope. In particular, the work focuses on classification and interpretation of features derived from the phonocardiographic (PCG) signal by using advanced signal processing techniques. LÄS MER
