| Abstract(in English) | As countermeasures for eavesdropping in wireless communications, data encryption techniques are generally used. On the other hand, Wyner pointed out that secret communications can be achieved without encryptions utilizing noise effect generating in wiretap channel. However, the study so far has been within analysis to prove the possibility and no practical method to realize the theory has been presented yet. In this paper, we therefore propose the practical scheme to realize it assuming fading channel in mobile radio channel. The method is to realize secret communications by adopting adaptively-controlled transmission system by which significant amount of gap is generated between BERs (Bit Error Rates) at authorized receiver and eavesdropping receiver. To evaluate the effectiveness of the proposed system quantitatively, computer simulations are carried out. As the results, we show that the secret communication by the proposed system is practically possible. |
