Abstract :
In this paper, we have presented a joint design of multiuser scheduling and transmit antenna selection for the multiuser MIMO system employing block diagonalization with linear transceivers. Based on these criterions, we have proposed a successive multiuser scheduling scheme. Simulation results show that maximizing global averaged eigenvalues (MGAE) is suitable for multiuser scheduling scheme in term of sum rate capacity. As for the transmit antenna selection schemes, maximizing global minimum eigenvalue (MGME) is preferred at higher SNR and MGAE is suitable at lower SNR.
