Recent work has shown that capacity of a multiple-antenna MIMO system is increased linearly with the number of transmitter antennas in fading channels.For a poor scattering environment

the low-rank channel may result in a substantial degradation of capacity although fading is independent.In this situation

antenna selection is an effective way to reduce cost.Capacity of a low-rank MIMO channel with antenna selection is studied.The results of simulation show that antenna selection of transmitter not only can increase capacity

but can also reduce complexity and cost of RF chains for given channels.Antenna selection of receiver also can reduce cost under the condition of not decreasing capacity.
