A Survey of Advances in MIMO Techniques for Mobile Communication

Wireless communication is evolving at a greater pace with the continuous introduction of new services and this hiking graph of technologies also requires update in Antenna systems. This paper overviews crucial advancements in the MIMO(Multiple- Input Multiple-output) systems and in context to this, key aspects of single user MIMO and multiuser MIMO are also discussed. Overview of Open loop and closed loop, SU (single user) MIMO is provided with analysis of Data Rate maximization in MIMO along with review of Uplink and downlink technologies of MU (Multi User)-MIMO. This paper also provides insight about convex optimization techniques in MIMO design.
