چکیده
Multiple-input multiple-output (MIMO) systems are anticipated to be widely employed to address the ever increasing capacity demands for wireless communication systems. MIMO technology is one solution to attain this by transmitting multiple data streams from multiple antennas. Increasing the number of transmit and receive antennas enables to improve system performance , but the multiple RF chains associated with multiple antennas are costly in terms of size, power and hardware.Therefore,an efficient scheme is required for the systems with large antennas to reduce the hardware and computational costs. An efficient approach to achieve this goal is the fast transmit antenna. For low-rank channels, transmit antenna selection can increase the capacity compared to a full-complexity system. In this paper we have studied different antenna selection schemes and the performances are compared in an analytical manner. Keywords-MIMO, Antenna Selection, Channel Capacity, SNR
