Abstract

The goal of the test bed is to characterize performance over realistic propagation and interference environments. These environments have statistical variations on the performance that are a function of the absolute position of the antennas. Manually moving the antennas to collect statistically significant observations and data is not a creative use of engineering time. For this reason we have chosen to develop a test bed that has the ability to remotely move antenna positions. This remote control will allow significant amounts of data to be collected without noteworthy man power being spent in monitoring and implementing the tests. The robotic system will be implemented with Lego components to keep the cost and electro-magnetic interaction with equipment to a minimum. A MIMO test bed must be able to provide benchmarks for performance to give context for the measured results. In simulation studies, the benchmarks are provided by Claude Shannon and information theory. In simulation studies, the channel is known and the benchmarks are easily computed. In experimental systems the channel is unknown, hence reporting results without a channel measurement and capacity estimation is not useful. For this reason we have chosen to develop a test bed that has the ability to quasi simultaneously measure system capacity and measure performance of realistic coding and modulation schemes on the measured channels.
