摘要： A MIMO signal generator is adapted to generate a MIMO signal is provided. The MIMO signal generator comprises a signal generator, a signal divider and a frequency shifter. The signal generator is adapted to generate a plurality of frequency shifted partial MIMO signals within a first signal generator output signal. The frequency shifted partial MIMO signals being arranged on the frequency axis in a non-overlapping manner. The signal divider is adapted to divide the first signal generator output signal into a plurality of signal paths. The frequency shifter preferably comprises a frequency shifting device in at least one of the plurality of signal paths. The frequency shifting devices are adapted to shift the frequencies of the plurality of frequency shifted partial MIMO signals to a joint carrier frequency, resulting in a plurality of partial MIMO signals, forming the MIMO signal.
