Abstract
A window function arithmetic operation unit performs a convolution arithmetic operation of the frequency characteristics of a window function with the input of modulation signals which are output by a layer frequency domain signal generation unit. A beam forming equivalence arithmetic operation unit performs an arithmetic operation process equivalent to the beam forming process with the input of propagation channel characteristics of each path which are output by a fading setting unit, and a Fourier transform unit performs Fourier transform with the input of the arithmetic operation results. An arithmetic operation unit obtains spectrum information of signals to be received in receiving antennas, converts the obtained spectrum information into signals in the time domain through inverse Fourier transform processes performed by a time domain signal generation unit. A shift addition unit shifts and adds the converted signals, to generate received signals of the receiving antennas.
