Relay-Assisted Transmission with Fairness Constraint for Cellular Networks
Abstract—We consider the problem of relay-assisted transmission for cellular networks. In the considered system, a source node together with n relay nodes are selected in a propo...

Switch-And-Stay Transmit Diversity for Cooperative Decode-And-Forward Systems
—We consider the application of switch-and-stay transmit diversity (SSTD) to a three-node cooperative diversity system with decode-and-forward relaying. The basic idea of SSTD ge...
