Multiple Input Multiple Output systems has better performance which can be achieved without using additional transmit power or bandwidth extension. However, it requires additional high-cost RF modules are required as multiple antennas are employed. To reduce the cost associated with the multiple RF modules, antenna selection techniques can be used to employ a smaller number of RF modules than the number of transmit antennas. This paper presents analytical and simulative investigations on an optimum antenna selection technique using channel state information.

In this paper, we have used transmission techniques that can be used to exploit the CSI on the transmitter side. The CSI can be known completely or partially. Sometimes, only statistical information of the channel state is available. We have exploited such information for optimum antenna selection and hence for achieving high the channel capacity. Simulation results show the channel capacity that the channel capacity increases in proportion to the number of the selected antennas. When the SNR is less than 10dB, the selection of three antennas is enough to warrant the channel capacity as much as the use of all four antennas. As this antenna selection method requires too much complexity depending on the total numbers of available transmit antennas.
