Abstract (in Japanese) (See Japanese page) 
(in English) As a physical layer security technique, we have proposed spatially-selective modulation (SSM) which consists of multiple transmitting antennas and a single receiving antenna. In the method, the modulated signal is decomposed into multiple phase-modulated signals having constant amplitude, and the signals are transmitted from each of the transmitting antennas. Properly controlling the phase of the transmitted signals allows only at the location of the legitimate receiver to receive the desired modulated signal. The previous study on SSM has used a statistical channel model assuming Rayleigh fading for the quantitative analysis of the performance. In this paper, the propagation characteristics in an indoor environment are calculated theoretically by the ray-tracing analysis which can evaluate the performance of SSM for spatial geometry and the distribution of the transmitter and the receiver. Based on the characteristics obtained from the analysis, we evaluate the secret transmission performance and verify the effectiveness of SSM.
