MIMO Signalling

rxStationPhoto-page-001Under our University program we developed a 4 x 4 multiple antenna test system to evaluate the MIMO channel potential in the 900MHz band. Over the last decade MIMO has gained widespread acceptance a major technology to significantly enhance spectral efficiency. Active research into “massive MIMO” for applications the mm-wave bands promise to resolve the looming spectral crowding. Some of HCDC’s MIMO measurement campaigns are documented in the reference below.
