Research on capability of antenna subset selection in MIMO system

Antenna subset selection in MIMO wireless systems discussed are discussed.First,we establish the channel model and analyse it.Second,we analyse the instances that channel matrix are not full-rank and adopt several schemes to choose transmit antennas and receive antennas.Last,we educe the effects of different antenna selection on channel capacity.Simulation results indicate that the transmit antenna selection can increase channel capacity,the selection of the receiver and transmitter antennas simultaneously can reduce complexity,but can not improve the channel capacity.
