Query: Characterization of Effective Capacity in Antenna Selection MIMO Systems   In this Paper, the effective capacity of a multiple-input multiple-output
(MIMO) system in two different cases with receive antenna selection (RAS) and
transmit antenna selection (TAS) schemes is investigated. A closed-form
solution for the maximum constant arrival rate of this network with statistical
delay quality of service (QoS) constraint is extracted in the quasi-static
fading channel. This study is conducted in two different cases. When channel
state information (CSI) is not available at the MIMO transmitter,
implementation of TAS is difficult. Therefore, RAS scheme is employed and one
antenna with the maximum instantaneous signal to noise ratio (SNR) is chosen at
the receiver. On the other hand, when CSI is available at the transmitter, TAS
scheme is executed. In this case one antenna is selected at the transmitter.
Moreover, an optimal power-control policy is applied to the selected antenna
and the effective capacity of the MIMO system is derived. Finally, this optimal
power adaptation and the effective capacity are investigated in two asymptotic
cases with the loose and strict QoS requirements. In particular, we show that
in the TAS scheme with the loose QoS restriction, the effective capacity
converges to the ergodic capacity. Then, an exact closed-form solution is
obtained for the ergodic capacity of the channel here.
