— We consider relaying strategies for two-way relay channels, where two terminals transmits simultaneously to each other with the help of relays. A memoryless system is considere...
Abstract— Cooperative diversiy is a promising technology for future wireless networks. In this paper, based on the moment generating function (MGF), we derive exact closed-form e...
—We consider a system with a single base station communicating with multiple users over orthogonal channels while being assisted by multiple relays. Several recent works have sug...
— The performances in cooperative communications depend on careful resource allocation such as relay selection and power control, but traditional centralized resource allocation ...
Ultrasound has been proposed as out-of-band channel for authentication of peer devices in wireless ad hoc networks. Ultrasound can implicitly contribute to secure communication ba...
