Introduction
The scope of PHYCOM is to provide efficient PHY-layer real-time implementations of modern bit-intensive communication systems, encompassing as well the design of RF transceivers. The members of the department have a proven expertise in addressing the digital design challenges of processing demanding systems. PHYCOM encapsulates all levels of PHY-layer prototyping:
- Fundamental research on DSP algorithms
- Conception of system architecture
- High-level system modelling in Matlab
- Real-time FPGA design and implementation
- On-board code integration and interfacing
- RF/analogue transceiver development
- System-level testing and validation in close to real-life conditions
