Claim Text:
1. A verification device for verification of a Line of Sight (LOS) Multiple-Input Multiple-Output/Single-Input Multiple-Output (MIMO/SIMO) system wherein the LOS MIMO/SIMO system includes at least one transmitter unit connected to at least a first transmit antenna, the LOS MIMO/SIMO system also includes a first receive antenna connected to a first down-converter arranged to output a first down converted signal and a second receive antenna connected to a second down-converter arranged to output a second down-converted signal, said first and second receive antennas being arranged to receive a first signal with reference symbols transmitted from at least one of said at least first transmit antenna, the verification device being arranged: to obtain a phase difference between the first signal as received in the first and second receive antennas respectively by comparing the first down-converted signal and the second down-converted signal with the reference symbols; and to obtain a gain ratio between the first signal as received in the first and second antennas respectively by comparing the first down-converted signal and the second down-converted signal with the reference symbols.
