Multiple-Input-Multiple-Output (MIMO) wireless communication architecture promises an approach to achieve high bandwidth efficiencies and allow robustness against channel fading and interference over conventional single antenna systems. MIMO wireless channels can be simply defined as a link for which both transmitting and receiving ends equipped with multiple antenna elements. This advanced technology has potential to resolve the problem in traffic capacity for the future networks. However, the performance of MIMO system has been considered that it strongly depends on the propagation environment. In this paper, the performance of MIMO wireless communication system in terms of channel capacity characteristics is studied. Both Minimum Mean-Squared Error (MMSE) and Maximum Likelihood Detection (MLD) algorithms for the adaptive control of weight coefficients are considered. The effects of antenna configurations such as the antenna polarization and the element spacing of both base station (BS) and mobile terminal (MT) antennas are evaluated. The reliability and the effectiveness of MIMO system are also represented compared with a conventional Single-Input-Single-Output (SISO) one.
