Signal processing correcting coupling between antennas in a 2x2 MIMO context

The aim of this paper is to study a 2 x 2 multiple-input multiple-output (MIMO) with Alamouti technique and antenna´s coupling phenomena at the transmitters and at the receivers. The motivation of this study is to show and to explain the impact of two different symbols estimation models over the coupling effect on the performances of the studied system. Some mathematical equations will demonstrate the behavior of the system and some curves will prove the results by simulations.
