| Abstract(in English) | In this paper, we consider a secrecy transmission scheme in the physical layer, employing multi-band transmitters available of dynamic power allocations and channel selections. In existing secrecy transmission schemes, there are few schemes for avoiding a channel being wiretapped. The existing information dispersal schemes, which have been considered for enhancing secrecy capacity, makes difficult for eavesdroppers to decode a message correctly by using redundant information or randomized modulation schemes. By contrast, we consider utilizing multi-band transmitter for distributing each confidential message for each receiver over multiple frequency channels and the amount of information leaking out can be decreased. Moreover,we aim to improve the secrecy capacity by using an adaptive power allocation and channel selection method based on the channel condition of each user. By using computer simulations, we could verify that the proposed method improves the performance in terms of secrecy capacity in eavesdropping compared with the previous methods using single-band transmission. |
