Abstract
Four (=M) transmission information signals are output from transmission information generating unit to linear transform unit, where they are transformed into synthesis signals by linear transform expressed by multiplication by a 2×4 matrix having complex numbers as elements. Signal processors perform signal processing corresponding to the modulation technique of test target on synthesis signals. On the resultant signals, 2×2 channel processing unit performs 2×2 pseudo channel processing, thereby forming equivalent M×N channels. Parameter setting unit sets information necessary to acquire desired M×N channel characteristics as the synthesis characteristics of linear transform unit and N×N channel processing unit.
