A highly flexible digital radio testbed and 60 GHz application examples

In this paper we present a modular digital radio testbed, which has been developed to enable the implementation of novel wireless transmission concepts and signal processing algorithms. The highly flexible and reconfigurable hardware comprises a commercial FPGA platform, a self-developed converter board as well as various plug-on clock and RF modules. To illustrate the capabilities of the testbed, two application examples are presented: real-time channel sounding and 60 GHz point-to-point transmission with higher order modulation.
