Abstract
A verification device for a LOS MIMO/SIMO system which comprises a transmitter unit connected to a first and a second transmit antenna and a first receive antenna connected to a first down-converter which outputs a first down converted signal and a second receive antenna connected to a second down-converter which outputs a second down-converted signal. The first and the second receive antennas receive a first signal with reference symbols transmitted from one of said first and second transmit antennas, and the verification device obtains the phase difference between the first signal as received in the first and the second receive antennas respectively by comparing the first down-converted signal and the second down-converted signal with the reference symbols.
