The Telecommunications Circuits Laboratory (TCL) focuses on the development of circuits and systems for digital signal processing with a strong focus on systems and applications in the area of telecommunications. Our research is concerned with the development of low-complexity signal processing algorithms and communication technologies, with the design of technology demonstrators and prototypes for performance assessment, and with the hardware-efficient, low-power implementation of digital integrated circuits for various telecommunication systems. In our work, we focus on a system-level perspective and we try to consider both algorithm and implementation aspects jointly. In particular, we are interested in new, spectrally efficient communication technologies such as multi-antenna wireless communication systems which serve a wide range of applications from cellular systems to local high speed wireless networks. Furthermore, we are interested in wireless and wireline communication links with very high throughput and processing requirements that challenge even the most advanced silicon process technologies. Finally, we are interested in linking concepts from communications (e.g., coding) to future deep submicron integrated circuit technologies which are likely to suffer from reliability issues.
