= Real-Time Physical Layers = Our real-time physical layers are developed in System Generator. This is a block based design tool for MATLAB's Simulink. It is provided by Xilinx and generates corresponding HDL once synthesized. Our current real-time PHY implements OFDM. Read more about the design on [wiki:OFDM its page]. The source code and model are available in [source:/ResearchApps/PHY/MIMO_OFDM the repository].
