Rights accessOpen Access
In this paper a new measurement setup to obtain the characteristic channel matrix of a MIMO radio system is presented using a small and non intrusive device able to characterize two antennas and therefore obtaining the characteristic channel matrix of a MIMO radio system of Nx2 antennas without using a receiver for each port. The extension to a system of more than two output elements can be easily achieved increasing the complexity of the switching device. To validate the new methodology presented here a 2x2 MIMO channel matrix has been characterized comparing the singular value distribution obtained with a traditional measurement procedure.
