Modern systems of wireless communications have limited capacity and processing techniques are required more sophisticated in order to improve system performance. One of the techniques in vogue is the application of MIMO (Multiple Input Multiple Output), known to improve the channel capacity and or the probability of bit error. This paper is the comparison of two techniques for MIMO systems. The first technique using a series of antennas on the side of the terminal (and therefore much RF chain) is known to improve system performance and that there is a feedback loop containing the state of the channel or not.
