About the Edition

There is great interest in the research community supporting the use of multiple antennas at the transmitter and receiver of a wireless link. Such systems can support the ever-growing demand for capacity and data services. Multiple antenna systems can effectively meet these demands by supporting higher data rates and/or providing increased channel reliability.Optimizing the downlink transmission of a multiple antenna system requires the availability of channel information at the transmitter. This information can be used to customize the transmitted waveform to the channel using appropriate precoding. This thesis furthers the development of multiple antenna precoding by designing feedback schemes that support their use. Existing feedback schemes place restrictions that limit the inherent flexibility of multiple antenna systems. This thesis develops practical, flexible and efficient feedback schemes for both the single and multiuser case.

  Beamforming and Scheduling Strategies for Time Slotted Multiuser MIMO Systems Semih Serbetli and Aylin Yener Electrical Engineering Department The Pennsylvania State University University Park, PA [email protected] [email protected] Abstract—We investigate the problem of scheduling for the up-link of a time slotted multiuser MIMO system   for capacity improvement in a multiuser MIMO while a single-user MIMO is designed to improve a point-to-point link capacity [12]– [13]. In this paper, we propose a novel multiuser MIMO scheme which exploits user diversity for scheduling users and adapts the transmit beamforming based on the feedback information. We also investigate

Among these schemes, aligning the interference over spatial dimension is the most practical approach. Therefore, most literatures about IA focus on the multi-user MIMO systems. In this work, we provide a brief review of available literatures on IA in multi-user MIMO ://   Nearly Doubling the Throughput of Multiuser MIMO Systems Using Codebook Tailored Limited Feedback Protocol GERHARD WUNDER1, JAN SCHRECK2 AND PETER JUNG2 1Fraunhofer Heinrich Hertz Institute, Einsteinu D Berlin, Germany 2 Technische Universita¨t Berlin Lehrstuhl fu¨r Informationstheorie und Theoretische Informationstechnik

feedback techniques for MU-MIMO-OFDM broadcast systems. Using the channel covariance and mean respectively, adaptive codebook techniques I and II are extensions of two adaptive codebook techniques proposed for single-user MIMO single-carrier systems. Technique III is a totally novel proposal   This paper provides a comprehensive overview of critical developments in the field of multiple-input multiple-output (MIMO) wireless communication systems. The state of the art in single-user MIMO (SU-MIMO) and multiuser MIMO (MU-MIMO) communications is presented, highlighting the key aspects of these technologies. Both open-loop and closed-loop SU-MIMO systems are discussed in this paper
