Abstract

Abstract

Antenna Selection (AS) technique and Virtual MIMO(VMIMO) technique have been widely used in uplink transmission, where the User Equipment (UE) has two antennas but only one Radio Frequency (RF) link. With a view to fully take the advantages of these two techniques, in this paper we apply the AS technique in the VMIMO system, as VMIMO-AS system. However, when both the VMIMO and the AS are applied, always choose the better antennas from the users to form the VMIMO could not guarantee the optimal performance. In this paper, the UE pairing algorithms for the VMIMO system with antenna selection was studied. Different user pairing algorithms are proposed and their throughput and fairness performance are compared. Simulation results show that the first UE should be selected by using the AS technique. Comparably, the selection of the pairing user does not need the AS process, considering the trade-off between the complexity and performance.
