In this paper, we analyze the performance of an adaptive Multiple Input Multiple Output (MIMO) system employing transmit antenna selection and rate adaptation based on channel state information (CSI). Imperfections in CSI due to estimation error and feedback delay are considered. Since CSI is imperfect, the rate of transmission is chosen in order to meet a target outage probability. The average throughput is evaluated for various cases of imperfect CSI using Monte Carlo simulations. Simulation
