The equipment in the laboratory allows the realization of highly-reliable wireless machine-to-machine communication links. Wireless signal processing algorithms can be validated in real time on a software defined radio (SDR) platform.
The infrastructure includes
• multiple SDR transmitter and receiver for multiple-input multiple-output (MIMO) and for massive MIMO systems
• field programmable gate arrays (FPGA) computation units for high-speed signal processing
• rubidium clocks for accurate phase and time-synchronization between multiple SDR nodes
• antenna arrays to realize massive MIMO systems with distributed antenna groups
