Abstract
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. The purpose of 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. However, the use of these antennas on the terminal requires a lot of power because the remains of additional RF chains. The second one is for the terminal to choose the best antenna corresponding to the channel conditions. For the uplink, this requires a return to the channel state radio base station to mobile. The performance will always be suboptimal compared to using multiple channels in reception. But the terminal would need to maintain single RF chains which potentially save a lot of power.
