Performance of Antenna Selection Algorithm Based Cost Function for MIMO System

In this paper, two novel antenna selection algorithms based cost function for multiple-input multiple- output (MIMO) wireless system are introduced, which are named Increasing selection Based Cost Function (IncBCF) and Decreasing selection Based Cost Function (DecBCF), respectively. The proposed antenna selection algorithms are only considered at the receiver, which aim at maximizing channel capacity. Through the simulation results, it can be seen that the DecBCF algorithm obtains almost the same capacity as the optimal selection algorithm while retaining lower computational complexity. Further more, the results show that the proposed algorithms provide better performance than the existing suboptimal antenna selection algorithms.
