Physical-layer Implementation of High Performance Communication Systems (PHYCOM)


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
