To improve the transmission rate of multi-antenna relaying systems, a joint optimization algorithm based on rate maximization and antenna selection is proposed. In order to deal with the coupled amplifying-and-forwarding factors and antenna selection sequence, this joint optimization problem is handled by separating the two variables, and its analytical solution is derived according to optimization theorem. Simulation results show that, the proposed algorithm significantly outperforms the conventional methods in terms of system data rate.
