Low complexity decoding schemes for MIMO systems

Abstract : The use of MIMO antennas is a technique that allows to exploit in a very effective way the spatial and temporal diversity in certain systems of communication, of which the wireless communication systems. The main advantage of this technique is a good spectral efficiency. Nowadays, the mobile radio channel is increasingly used to transmit all type of information and methods allowing a more effective use of the spectrum have a fundamental importance. Today, the well-known reception algorithms are very complex, even as regards the MIMO systems with the simplest space-time codes. This complexity remains one of the main obstacles in the real exploitation of this technique. This thesis presents a detailed study of the complexity, the performance and the most interesting aspects of the behavior of the reception algorithms for MIMO decoding. This study presents a quick mean for a possible architectural conception adapted to this problem. Among the subjects presented in this thesis, an in-depth study of the performance and the complexity of these algorithms was realized, having for objective to acquire enough knowledge to be able to choose, among the large number of known algorithms, the best adapted to every particular system. Improvements in the known algorithms were also proposed and analyzed
