Wireless Testbed Receiver

These days, the demand for mobile transmission bandwith seems to be a never ending story. To get insights into the real world, wireless transmission measurements and not only simulations of mobile communication systems are necessary. For this task, the Vienna Wireless Testbed has been developed. To keep pace with future developments, the testbed has to be extended and updated constantly. Furthermore, before publishing measured results, one has to make certain that they are not degraded due to impurities or hardware that does not work properly. In this thesis, the receiver, which is a main part of the Vienna Wireless Testbed, is set up for future tasks. Major improvements in quality and flexibility are achieved by replacing the analog to digital conversion plug in board. Furthermore, applying the capabilities of a novel timing responsible for triggering, a fast and secure way of transmitting huge numbers of blocks within short periods of time is achieved. Furthermore, a methodology for rapidly testing the receiver’s radio frequency front end hardware is developed. Moreover, measurement results for the current testbed configuration are shown. The receiver hardware is tested in particular with an orthogonal frequency-division multiplex signal which is also used in the next generation mobile communication standard, namely Long Term Evolution (LTE). An outlook on what steps could be taken to improve the performance of the testbed receiver is given at the end of this thesis.
