Optimization of Multiuser MIMO Networks with Interference

Maximizing the total mutual information of a multiuser multiple-input multiple-output (MIMO) system with interference is a well-known and challenging problem. In this paper, we consider the power control problem of finding the maximum sum of mutual information for multiuser MIMO systems with equal power allocation at each link. A new and powerful global optimization method using a branch-and-bo...

Precoding for Multiuser MIMO

Future Wireless Networks are expected to adopt multi-user multiple input multiple output (MU-MIMO) systems whose performance is maximized by making use of precoding at the transmitter. This chapter describes the recent advances in precoding design for MU-MIMO and introduces a new technique to improve the precoder performance. Without claiming to be comprehensive, the chapter gives deep introduc...

Multiuser - MIMO for capacity gain in Fi-Wi hybrid networks

Fiber to the Rooms paradigm is gaining a lot of attention recently. In this paradigm, the last mile wireless (viz., IEEE 802.11x) connectivity, backed by optical fiber infrastructure, supports uncompressed high data rate while rendering seamless mobility and higher frequency reuse. To provide cost effective solution, Access Points (AP) in each room are replaced by distributed antennas. A centra...

Cooperative Transmission for the Downlink of Multiuser Mimo Cellular Networks

COOPERATIVE TRANSMISSION FOR THE DOWNLINK OF MULTIUSER MIMO CELLULAR NETWORKS Yakup Kadri Yazarel M.S. in Electrical and Electronics Engineering Supervisor: Asst. Prof. Dr. Defne Aktaş August, 2007 In this thesis, we propose a distributed transmission scheme for the downlink of a multiuser system. The base-stations (BSs) cooperate with each other with limited, local message-passing to find the ...
