On Building Testbeds
Sebastian Caban, Christian Mehlführer Dipl.-Ing., Markus Rupp, Martin Wrulich · 2011
This chapter introduces multiple-input multiple-output (MIMO) testbed design before reporting on possible pitfalls regarding testbed design in general. Global positioning system (GPS) units and rubidium frequency standards are located at the transmitter and receiver site to allow for accurate timing and frequency synchronization if necessary. Of course, one could argue that our testbed is just another approach to building a piece of “publishable” MIMO measurement hardware. Therefore, the engineering part of this chapter was kept short, whilst still describing all the parts of our testbed before listing possible issues regarding testbed design in general. On the other hand, only very few groups nowadays are continuously producing results based on testbeds owing to the extremely time-consuming efforts involved and the required educational profile ranging from computer engineering through telecommunication engineering and electrical engineering to even mechanical engineering in many cases.
