Application of Transmit Antenna Selection in Wireless Local Area Networks

In this paper, we investigate the application and benefits of Transmit Antenna Selection in 802.11n MIMO systems. Our goal is to find a combination of transmitting antennas, which can provide high system reliability. In addition, we consider a channel with partial Channel State Information (CSI). Using a simulation model we study the behavior of the system for a particular Transmit Antenna Selection (TAS) algorithm. Finally, we present the results from different scenario simulations with different number of transmitting and receiving antennas and demonstrate to what extend the imperfect CSI affects the performance of the wireless system.
