| Abstract(in English) | In this paper, a channel generation method for area-spectral efficiency evaluation of wireless systems with spatial signal processing is proposed. It generates multipath channels using simplified 2-D raytracing with quite small computational complexity in order to treat antenna directivity or digital beamforming, and to apply to various node locations. Then suitable refrection and transmission coefficients of the proposed method are searched so that the characteristics of multipath channels, i.e., delay spread, Rician factor, delay spread in scattered waves and anglular spread, generated by the proposed method meet to those of real environment. There are searched through comparison between the proposed method and 3-D raytracing simulations assuming an indoor LOS environment. Simulation results reveal the proposed method with a refrection coefficient of 0.15 and a transmission coefficient of 0.2 gives multipath channels similar to those given by the 3-D raytracing simulations. |
