Abstract:
The present application relates to a technique for reducing the circuit scale of a testing device having a function of performing a fading process with respect to a propagation channel of S×U channels assumed between transmitting and receiving antennas, using a terminal compatible with MIMO for transmitting a downlink signal from a base station to a mobile terminal with the number of base station-side antennas S and the number of terminal-side antennas U, or a circuit substrate, an integrated circuit and the like built into the terminal, as a test object. The multiplication arithmetic operation of the characteristics of the propagation channel and the modulation signal is performed in the frequency domain, and a time domain signal is generated from the arithmetic operation result. It's possible to considerably reduce the scale of a circuit that performs inverse Fourier transform and the scale of a circuit that generates propagation channel characteristics.

Claim (Index 3):
The device for testing a MIMO scheme system according to  claim 1 ,\n wherein the Fourier transform unit includes\n a Fourier transform arithmetic operation unit that performs Fourier transform arithmetic operation processes with the input of the L unit\u2032 worth of the propagation channel characteristics, and \n an interpolation unit that performs interpolation processes in the frequency axis with the input of arithmetic operation results of the Fourier transform arithmetic operation unit.
