Multiple antennas have played an essential role in spatial multiplexing and diversity
transmission for a wide range of communication applications. Most advances in the design …

In downlink multi-user beamforming, a single basestation is serving a number of users
simultaneously. However, energy intended for one user may leak to other unintended users …

We study the robust transceiver optimization in downlink multiuser multiple-input multiple-
output (MU-MIMO) systems aiming at minimizing transmit power under probabilistic quality …

We investigate antenna-grouping algorithms, which are hybrids of beamforming and spatial
multiplexing. We partition transmit antennas into several groups and use beamforming in a …

This paper investigates the symbol error rate (SER) performance of the multiple-input
multiple-output (MIMO) multi-channel beamforming (MB) in the general double-scattering …

Multiple-input multiple-output (MIMO) channels are an abstract and general way to model
many different communication systems of diverse physical nature. In particular, wireless …

In this paper, we analyze the diversity performance of source-relay joint precoding in spatial
multiplexing (SM) multiple-input-multiple-output (MIMO) amplify-and-forward (AF) relaying …

We consider nonlinear signal processing algorithms for downlink multiple-input multiple-
output (MIMO) systems with multiple-antenna users. The design goal is to improve bit error …

This paper presents a general expression for the marginal distributions of the ordered
eigenvalues of certain important random matrices. The expression, given in terms of matrix …

In this paper, a MIMO system with finite-bit feedback based on fixed constellations is
considered. Based on performance analysis of the system, an optimal operating system with …
