Sammanfattning
Development of wireless networks enforce research on new system designs, always in pro fit of
improving certain features. A distributed MIMO network is de fined by moving the antennas
away from the base station, gaining spatial degrees of freedom. This technique has proven
to meliorate some of the experienced diffculties in a collocated MIMO system, inspiring further
research. In profi t of understanding the capacity and limitations of such a network it is
advantageous to enable actual measurements by building a testbed. Further, 1-bit receiver
technology is promising in reducing analog system complexity, migrating as much as possible
to digital domain at the central unit. This project entails research on the implementation
of a distributed MIMO 1-bit RF receiver, including measurements and hardware analysis. It
proves that such a system is in fact realizable with off-the-shelf components, although demands
further development to gain
exibility.
