Abstract
While the field of MIMO transmission has been explored over the
past decade mainly theoretically, relatively few results exist on
how these transmissions perform over realistic, imperfect
channels. The reason for this is that measurement equipment is
expensive, difficult to obtain, and often inflexible when a
multitude of transmission parameters are of interest. This paper
presents a flexible testbed developed to examine MIMO algorithms
and channel models described in literature by transmitting data at
2.45GHz through real, physical channels, supporting
simultaneously four transmit and four receive antennas. Operation
is performed directly from Matlab allowing for a cornucopia of
real-world experiments with minimum effort. Examples measuring bit
error rates on space-time block codes are provided in the paper.
