Antenna selection can reduce the number of the RF chains as well as the complexity of the system. This article explains the aim of antenna selection in a Multiple-Input Multiple-Output (MIMO) system but applied in an LTE environment. However, these systems carry bad consequences such as the number of RF chains associated with multiple antennas, which are costly in terms of size, power and hardware. In this report, an introduction to a MIMO system is given, specifying the case of a Distributed Antenna System (DAS). The antenna selection algorithms applied at the transmitter side of an LTE system are the Mutual Information based algorithm, the path loss based algorithm, the total norm based algorithm and the norm based algorithm. The results shown in this paper are obtained through simulations executed on a MATLAB-based system level simulator from the Vienna University of Technology. The results show that a DAS system can achieve better performance than a system where the transmit antennas are collocated in the base station. Furthermore, any of the antenna selection algorithms improves the throughput, both cell and user throughput,
compared to the same system without antenna selection.
