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&#xd7;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&#xd7;2 channel processing unit performs 2&#xd7;2 pseudo channel processing, thereby forming equivalent M&#xd7;N channels. Parameter setting unit sets information necessary to acquire desired M&#xd7;N channel characteristics as the synthesis characteristics of linear transform unit and N&#xd7;N channel processing unit.
