In this work, we study antenna selection criteria and algorithms for multiple-input multiple-output (MIMO) wireless systems using channel data produced by the specialized software MIMObit. We begin by summarizing conventional performance metrics for MIMO systems and presenting several antenna selection algorithms. We run these algorithms in MALAB, assuming that, when some antennas are not selected for operation, the channel coefficients of the selected ones do not change. However, this assumption (which is conventionally made in the literature) does not hold true in reality. To develop a more realistic solution for the antenna selection problem, we use MIMObit which offers an integrated platform that helps us simulate MIMO systems with custom created dipoles under different propagation environments and generate the corresponding channel coefficients. Using MIMObit, we utilize the actual channel coefficients after the antenna selection process and show that the MIMObit-assisted antenna selection approach always outperforms the conventional one. In some cases, the performance gain is noticeable.
