Welcome to the Intelligent Signal Processing research centre (ISPRC) at the Communications Department, Faculty of Electronics, Telecommunications and Information Technologies, of the Politehnica University of Timisoara! ISPRC has been actively teaching courses, conducting research, and publishing results since 1986.

Current research interests are:

• Adaptive signal processing
• Coding
• Compression
• Data transmission
• Time-frequency representations
• Wavelets theory and applications
• Nonlinear signal processing
• Neural networks
• Digital watermarking
• Satellite navigation

In loving memory of Acad. Professor Adelaida Mateescu (1932-2009), the research lab of Signal Processing bears her name, under the aegis of Romanian Academy of Technical Sciences.

Several doctoral theses have been delivered in these research fields.
