PROBLEM TO BE SOLVED: To accurately simulate a transmission line with little computation amount by finding received signal data while using a signal level and arrival time data on the assumption that a path obeys with Rayleigh distribution rules. SOLUTION: A transmission parameter generating means 10 outputs a path signal using ray-tracing from an input signal, and an element wave angle generating means 16 outputs an element wave angle setting signal to a Doppler frequency generating means 18. An element wave level generating means 12 outputs an element wave level signal from the path signal or the like, while using Rayleigh distribution rules, an initial phase generating means 14 outputs an initial phase setting signal, and the Doppler frequency generating means 18 outputs a Doppler frequency setting signal. A received signal generating means 20 outputs a received signal from the respective output signals. The number of paths, the signal levels of respective paths, arrival time data and arrival direction data are found by ray-tracing and on the assumption that path obeys Rayleigh distribution rules, and received signal data are found, using the signal level and the arrival time data.
