| Outline of Final Research Achievements |
This research proposed a new channel state based a secure wireless communication mechanism to realize secure communication with a pre-equalization function in a physical layer. We focused on practical wireless communication environment, where multi-path signals are received at a receiver. The transmitter of the proposed scheme transmits an optimized signal to a receiver with pre-equalizing the signal according to the channel state between the transmitter and the receiver. Therefore, only the receiver that has the same channel state for the pre-equalizing can obtain the high quality signal from the transmitter, and can demodulate the signal correctly. As a result, eavesdroppers around the transmitter cannot equalize the received signal before a demodulation process for the received signal because they exist at a different place of the receiver. The numerical results show that the proposed scheme can realize secure communication in typical wireless channel models.
