| Outline of Final Research Achievements |
In wireless communication systems, cooperative communication technology has the potential to improve the communication performance of the entire network when a group of distributed nodes cooperates. In this study, we proposed methods that increase the degree of freedom in system design and exceed the conventional achievable performance by exploiting the degree of freedom of the data buffer, which has not been widely used in conventional wireless networks. In particular, we proposed cooperative communication protocols using buffers in combination with non-orthogonal multiple connections and full-duplex communication. The theoretical and numerical analysis confirmed the improved effective transmission rate, reliability, and confidentiality in the proposed schemes.
