Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we investigate power an allocation method for physical layer security based wireless communication with dummy signal. One of approaches to increase secrecy capacity is water filling principle based power allocation in orthogonal frequency division multiplexing (OFDM) based wireless communication. On the other hand, dummy based method can also achieve comparable secrecy capacity performance compared to the above method while it can achieve less complexity. In this method, dummy data and secret data are allocated to sub-carriers in OFDM signal and pilot signal is employed to inform the location of secret data. The pilot signal is designed for that legitimate receiver can detect it correctly on the other hand an eavesdropper can not detect it easily. In this paper, we propose power allocation for pilot signal and data (including dummy and secret data) signal. Numerical evaluation showed validity of the proposed power allocation method.
