ActivitiesThe Wireless System Lab (WisyLab) is dedicated to link-level simulation, DSP and FPGA design and implementation of physical layer (PHY) of wireless communication systems (GSM, UMTS, WiMax, LTE) using SDR (Software defined Radio) techniques.
Design packages, available at WisyLab, include complete DSP IDE tools from Texas Instruments, for C/C++/ASM programming and debugging, and FPGA EDA tools, for VHDL programming, simulation and implementation, from Xilinx, National Instruments MathWorks and Mentor Graphics. Over 30 DSP Starter-Kit TMS320C5402 boards are used for class teaching and fast prototyping. In addition, PXI virtual instrumentation devices (100 Msps arbitrary waveform generators and 64 Msps acquisition boards) from National Instruments PXI are employed for signal acquisition, generation and off-line processing. A 2x2 MIMO test-bed (scalable up to 4x4 nodes) with RF up/down converters and generators/analyzers has been developed in cooperation with WisyTech, spin-off of the Politecnico di Milano and the National Research Council (CNR).
System prototypes based on wireless sensor networks (IEEE 802.15.4/ZigBee) are currently under development for environmental monitoring. The architecture is tailored for a large number of applications with particular focus on traffic and parking monitoring (for intelligent transportation systems) and on seismic exploration through wireless networks of geophones.
