A Software-Radio Test-Bed for Measuring the Performance of DVB-S2 Receiver Circuits
Source: University of Patras
This paper presents a flexible and versatile DVBS2 test-bed that combines a set of automated signal generation and analysis instruments along with a powerful software radio processing unit for executing performance analysis experiments of DVB-S2 receiver circuits using realistic scenarios. The testbed provides a rich set of forward satellite channel impairments and also supports real DVB-S2 signals. All test-bed subunits are interconnected over a LAN and are controlled through a central processing unit, allowing fully automated data acquisition and processing of measurements collected from the various receiver circuits.
